NAME

       neomuttrc - Configuration file for the Mutt Mail User Agent

DESCRIPTION

       A  neomutt  configuration file consists of a series of “commands”.  Each line of the file may contain one
       or more commands.  When multiple commands are used, they must be separated by a semicolon (“;”).

       The hash mark, or pound sign (“#”), is used as a “comment” character. You can use  it  to  annotate  your
       initialization file. All text after the comment character to the end of the line is ignored.

       Single  quotes  (“'”)  and double quotes (“"”) can be used to quote strings which contain spaces or other
       special characters.  The difference between the two types of quotes is similar to that  of  many  popular
       shell  programs,  namely  that  a  single  quote  is  used  to  specify a literal string (one that is not
       interpreted for shell variables or quoting with a backslash [see next paragraph]),  while  double  quotes
       indicate  a  string  which  should  be  evaluated.  For example, backticks are evaluated inside of double
       quotes, but not single quotes.

       \ quotes the next character, just as in shells such as bash and zsh.  For example, if want to put  quotes
       (“"”)  inside  of  a  string,  you  can  use  “\”  to force the next character to be a literal instead of
       interpreted character.

       “\\” means to insert a literal “\” into the line.  “\n” and “\r” have their usual C meanings of  linefeed
       and carriage-return, respectively.

       A  “\”  at  the  end of a line can be used to split commands over multiple lines, provided that the split
       points don't appear in the middle of command names.

       It is also possible to substitute the output of a Unix  command  in  an  initialization  file.   This  is
       accomplished by enclosing the command in backticks (`command`).

       UNIX  environment  variables  can be accessed like the way it is done in shells like sh and bash: Prepend
       the name of the variable by a dollar (“$”) sign.

COMMANDS

       alias [-group name [...]] key address [, address [ ... ]]
       unalias [ *  | key ]

              alias defines an alias key for the given addresses. Each address will be resolved into  either  an
              email  address  (user@example.com)  or  a  named email address (User Name <user@example.com>). The
              address may be specified in either format,  or  in  the  format  “user@example.com  (User  Name)”.
              unalias  removes  the  alias  corresponding to the given key or all aliases when “*” is used as an
              argument. The optional -group argument to alias causes the aliased address(es) to be added to  the
              named group.

       group [-group name] [-rx EXPR [ ... ]] [-addr address [ ... ]]
       ungroup [-group name ] [ * | [[-rx EXPR [ ... ]] [-addr address [ ... ]]]

              group  is  used  to directly add either addresses or regular expressions to the specified group or
              groups. The different categories of arguments to the group command can be in any order. The  flags
              -rx  and  -addr  specify  what  the  following strings (that cannot begin with a hyphen) should be
              interpreted as: either a regular expression or an email address, respectively.  ungroup is used to
              remove  addresses or regular expressions from the specified group or groups. The syntax is similar
              to the group command, however the special character * can be used to empty a group of all  of  its
              contents.

              These  address groups can also be created implicitly by the alias, lists, subscribe and alternates
              commands by specifying the optional -group option.

              Once defined, these address groups can be used in patterns to search for and limit the display  to
              messages matching a group.

       alternates [-group name] regex [ regex [ ... ]]
       unalternates [ *  | regex [ regex [ ... ]] ]

              alternates is used to inform neomutt about alternate addresses where you receive mail; you can use
              regular expressions to specify alternate addresses.  This affects neomutt's  idea  about  messages
              from  you, and messages addressed to you.  unalternates removes a regular expression from the list
              of known alternates. The -group flag causes all of the subsequent regular expressions to be  added
              to the named group.

       alternative_order type[/subtype] [ ... ]
       unalternative_order [ *  | type/subtype] [...]

              alternative_order command permits you to define an order of preference which is used by neomutt to
              determine which part of a multipart/alternative body to display.  A subtype  of  “*”  matches  any
              subtype,  as does an empty subtype.   unalternative_order removes entries from the ordered list or
              deletes the entire list when “*” is used as an argument.

       auto_view type[/subtype] [ ... ]
       unauto_view type[/subtype] [ ... ]

              This commands permits you to specify that neomutt should  automatically  convert  the  given  MIME
              types  to text/plain when displaying messages.  For this to work, there must be a mailcap(5) entry
              for the given MIME type with the copiousoutput flag set.  A subtype of “*” matches any subtype, as
              does an empty subtype.

       mime_lookup type[/subtype] [ ... ]
       unmime_lookup type[/subtype] [ ... ]

              This  command permits you to define a list of "data" MIME content types for which neomutt will try
              to determine the actual file type from the file name, and not use a mailcap(5) entry given for the
              original  MIME  type.   For  instance,  you may add the application/octet-stream MIME type to this
              list.

       bind map1,map2,... key function
              This command binds the given key for the given map or maps to the given  function.  Multiple  maps
              may be specified by separating them with commas (no whitespace is allowed).

              Valid  maps  are:  generic,  alias, attach, browser, editor, index, compose, pager, pgp, postpone,
              mix.

              For more information on keys and functions, please consult the Mutt Manual. Note that the function
              name is to be specified without angle brackets.

       account-hook [!]regex command
              This  hook  is  executed  whenever  you  access  a  remote mailbox. Useful to adjust configuration
              settings to different IMAP or POP servers.

       charset-hook alias charset
              This command defines an alias for a character set.  This is useful to  properly  display  messages
              which are tagged with a character set name not known to neomutt.

       iconv-hook charset local-charset
              This  command  defines  a  system-specific  name  for  a  character set.  This is useful when your
              system's  iconv(3)  implementation  does  not  understand  MIME  character  set  names  (such   as
              iso-8859-1),  but  instead  insists  on being fed with implementation-specific character set names
              (such as 8859-1).  In this specific case, you'd put this into your configuration file:

              iconv-hook iso-8859-1 8859-1

       message-hook [!]pattern command
              Before neomutt displays (or formats for replying or forwarding) a message which matches the  given
              pattern  (or,  when  it is preceded by an exclamation mark, does not match the pattern), the given
              command is executed.  When multiple message-hooks match, they are   executed   in   the  order  in
              which they occur in the configuration file.

       timeout-hook command
              Run  a  command  periodically  when  Mutt checks for new mail.  This hook is called every $timeout
              seconds.

       startup-hook command
              Before neomutt opens the first mailbox when first starting, mutt will run the startup hook for the
              given command.

       shutdown-hook command
              Before neomutt is about to exit, and before the mailbox is closed, mutt will run the shutdown hook
              for the given command.

       folder-hook [!]regex command
              When neomutt enters a folder which matches regex (or, when regex is  preceded  by  an  exclamation
              mark, does not match regex), the given command is executed.

              When  several  folder-hooks match a given mail folder, they are executed in the order given in the
              configuration file.

       macro map key sequence [ description ]
              This command binds the given sequence of keys to the given key in the  given  map  or  maps.   For
              valid maps, see bind. To specify multiple maps, put only a comma between the maps.

       color object foreground background [ regex ]
       color index foreground background [ pattern ]
       uncolor index pattern [ pattern ... ]

              If  your  terminal  supports  color,  these  commands  can be used to assign foreground/background
              combinations to certain objects.  Valid  objects  are:  attachment,  body,  bold,  error,  header,
              hdrdefault,   index,  indicator,  markers,  message,  normal,  prompt,  quoted,  quotedN,  search,
              signature, status, tilde, tree, underline.  If the sidebar is enabled the  following  objects  are
              also  valid:  sidebar_divider, sidebar_flagged, sidebar_highlight, sidebar_indicator, sidebar_new,
              sidebar_spoolfile.  The body and header objects allow  you  to  restrict  the  colorization  to  a
              regular expression.  The index object permits you to select colored messages by pattern.

              Valid colors include: white, black, green, magenta, blue, cyan, yellow, red, default, colorN.

       mono object attribute [ regex ]
       mono index attribute [ pattern ]

              For  terminals  which  don't  support  color,  you  can still assign attributes to objects.  Valid
              attributes include: none, bold, underline, reverse, and standout.

       [un]ignore pattern [ pattern ... ]
              The ignore command permits you to specify header fields which you usually don't wish to see.   Any
              header field whose tag begins with an “ignored” pattern will be ignored.

              The  unignore  command  permits  you to define exceptions from the above mentioned list of ignored
              headers.

       lists [-group name] regex [ regex ... ]
       unlists regex [ regex ... ]
       subscribe [-group name] regex [ regex ... ]
       unsubscribe regex [ regex ... ]

              Mutt maintains two lists of mailing list address patterns, a list of subscribed mailing lists, and
              a  list  of  known  mailing  lists.  All subscribed mailing lists are known.  Patterns use regular
              expressions.

              The lists command adds a mailing list address to the list of known  mailing  lists.   The  unlists
              command  removes  a  mailing  list  from  the  lists  of  known and subscribed mailing lists.  The
              subscribe command adds a mailing list to the lists of known and  subscribed  mailing  lists.   The
              unsubscribe command removes it from the list of subscribed mailing lists. The -group flag adds all
              of the subsequent regular expressions to the named group.

       mbox-hook [!]regex mailbox
              When neomutt changes to a mail folder which matches regex, mailbox will  be  used  as  the  “mbox”
              folder, i.e., read messages will be moved to that folder when the mail folder is left.

              The first matching mbox-hook applies.

       mailboxes filename [ filename ... ]
       unmailboxes [ * | filename ... ]

              The mailboxes specifies folders which can receive mail and which will be checked for new messages.
              When changing folders, pressing space will cycle through folders with new mail.   The  unmailboxes
              command  is used to remove a file name from the list of folders which can receive mail.  If "*" is
              specified as the file name, the list is emptied.

       my_hdr string
       unmy_hdr field

              Using my_hdr, you can define headers which will be added to the messages  you  compose.   unmy_hdr
              will remove the given user-defined headers.

       hdr_order header1 header2 [ ... ]
              With  this  command,  you can specify an order in which neomutt will attempt to present headers to
              you when viewing messages.

       save-hook [!]pattern filename
              When a message matches pattern, the default file name when saving it will be the given filename.

       fcc-hook [!]pattern filename
              When an outgoing message matches pattern, the default file name for storing a copy (fcc)  will  be
              the given filename.

       fcc-save-hook [!]pattern filename
              This command is an abbreviation for identical fcc-hook and save-hook commands.

       send-hook [!]pattern command
              When  composing  a message matching pattern, command is executed.  When multiple send-hooks match,
              they are executed in the order in which they occur in the configuration file.

       send2-hook [!]pattern command
              Whenever a message matching pattern is changed (either by editing  it  or  by  using  the  compose
              menu),  command  is  executed.  When multiple send2-hooks match, they are executed in the order in
              which they occur in the configuration file.  Possible applications include setting  the  $sendmail
              variable when a message's from header is changed.

              send2-hook execution is not triggered by use of enter-command from the compose menu.

       reply-hook [!]pattern command
              When  replying  to  a  message  matching  pattern, command is executed.  When multiple reply-hooks
              match, they are executed in the order in which they occur  in  the  configuration  file,  but  all
              reply-hooks  are  matched  and  executed  before  send-hooks,  regardless  of  their  order in the
              configuration file.

       crypt-hook regex key-id
              The crypt-hook command provides a method by which you can specify the ID of the public key  to  be
              used  when  encrypting  messages  to  a certain recipient.  The meaning of "key ID" is to be taken
              broadly: This can be a different e-mail address, a numerical key ID, or  even  just  an  arbitrary
              search  string.   You  may  use multiple crypt-hooks with the same regex; multiple matching crypt-
              hooks result in the use of multiple key-ids for a recipient.

       open-hook regex "command"
       close-hook regex "command"
       append-hook regex "command"

              These commands provide a way to handle compressed folders. The given regex specifies which folders
              are taken as compressed (e.g.  "\\.gz$"). The commands tell Mutt how to uncompress a folder (open-
              hook), compress a folder (close-hook) or append a compressed mail to a compressed folder  (append-
              hook).  The  command  string  is  the  printf(3)  like  format  string,  and  it should accept two
              parameters: %f, which is replaced with the (compressed) folder name, and %t which is replaced with
              the name of the temporary folder to which to write.

       push string
              This command adds the named string to the keyboard buffer.

       set [no|inv|&|?]variable[=value] [ ... ]
       toggle variable [ ... ]
       unset variable [ ... ]
       reset variable [ ... ]

              These commands are used to set and manipulate configuration variables.

              Mutt  knows  four  basic  types  of  variables:  boolean,  number, string and quadoption.  Boolean
              variables can be set (true), unset (false),  or  toggled.  Number  variables  can  be  assigned  a
              positive integer value.

              String  variables  consist  of  any  number  of printable characters.  Strings must be enclosed in
              quotes if they contain spaces or tabs.  You may also use the “C” escape sequences \n  and  \t  for
              newline and tab, respectively.

              Quadoption  variables are used to control whether or not to be prompted for certain actions, or to
              specify a default action.  A value of yes will cause the action to be carried out automatically as
              if you had answered yes to the question.  Similarly, a value of no will cause the the action to be
              carried out as if you had answered “no.” A value of ask-yes will cause a  prompt  with  a  default
              answer of “yes” and ask-no will provide a default answer of “no.”

              The  reset  command  resets  all  given  variables to the compile time defaults.  If you reset the
              special variable all, all variables will reset to their compile time defaults.

       source filename
              The given file will be evaluated as a configuration file.

       spam pattern format
       nospam pattern

              These commands define spam-detection patterns from external spam  filters,  so  that  neomutt  can
              sort, limit, and search on ``spam tags'' or ``spam attributes'', or display them in the index. See
              the Mutt manual for details.

       unhook [ *  | hook-type ]
              This command will remove all hooks of a given type, or all hooks when “*” is used as an  argument.
              hook-type can be any of the -hook commands documented above.

       mailto_allow header-field [ ... ]
       unmailto_allow [ * | header-field ... ]

              These  commands  allow  the user to modify the list of allowed header fields in a mailto: URL that
              Mutt will include in the the generated message.  By default the list contains subject and body, as
              specified  by  RFC2368;  and cc, in-reply-to, and references to aid with mailto links from mailing
              lists.

PATTERNS

       In various places with neomutt, including some of the above mentioned  hook  commands,  you  can  specify
       patterns to match messages.

   Constructing Patterns
       A  simple  pattern  consists  of  an  operator of the form “~character”, possibly followed by a parameter
       against which neomutt is supposed to match the object specified by this operator.  For  some  characters,
       the  ~  may  be replaced by another character to alter the behavior of the match.  These are described in
       the list of operators, below.

       With some of these operators, the object to be matched consists of several e-mail  addresses.   In  these
       cases,  the  object  is  matched if at least one of these e-mail addresses matches. You can prepend a hat
       (“^”) character to such a pattern to indicate that all addresses must match in order to match the object.

       You can construct complex patterns by combining simple patterns with logical operators.  Logical  AND  is
       specified  by simply concatenating two simple patterns, for instance “~C neomutt-dev ~s bug”.  Logical OR
       is specified by inserting a vertical bar (“|”) between two patterns, for instance “~C  neomutt-dev  |  ~s
       bug”.   Additionally,  you  can  negate  a  pattern  by  prepending  a bang (“!”) character.  For logical
       grouping, use braces (“()”). Example: “!(~t neomutt|~c mutt) ~f elkins”.

   Simple Patterns
       Mutt understands the following simple patterns:

       ~A          all messages
       ~b EXPR     messages which contain EXPR in the message body.
       =b STRING   messages which contain STRING in the message body. If IMAP is enabled, searches for STRING on
                   the server, rather than downloading each message and searching it locally.
       ~B EXPR     messages which contain EXPR in the whole message.
       ~c EXPR     messages carbon-copied to EXPR
       %c GROUP    messages carbon-copied to any member of GROUP
       ~C EXPR     messages either to: or cc: EXPR
       %C GROUP    messages either to: or cc: to any member of GROUP
       ~d MIN-MAX  messages with “date-sent” in a Date range
       ~D          deleted messages
       ~e EXPR     messages which contain EXPR in the “Sender” field
       %e GROUP    messages which contain a member of GROUP in the “Sender” field
       ~E          expired messages
       ~f EXPR     messages originating from EXPR
       %f GROUP    messages originating from any member of GROUP
       ~F          flagged messages
       ~g          PGP signed messages
       ~G          PGP encrypted messages
       ~h EXPR     messages which contain EXPR in the message header
       ~H EXPR     messages with spam tags matching EXPR
       ~i EXPR     messages which match EXPR in the “Message-ID” field
       ~k          messages containing PGP key material
       ~l          messages addressed to a known mailing list (defined by either subscribe or list)
       ~L EXPR     messages either originated or received by EXPR
       %L GROUP    messages either originated or received by any member of GROUP
       ~m MIN-MAX  message in the range MIN to MAX
       ~n MIN-MAX  messages with a score in the range MIN to MAX
       ~N          new messages
       ~O          old messages
       ~p          messages addressed to you (as defined by alternates)
       ~P          messages from you (as defined by alternates)
       ~Q          messages which have been replied to
       ~r MIN-MAX  messages with “date-received” in a Date range
       ~R          read messages
       ~s EXPR     messages having EXPR in the “Subject” field.
       ~S          superseded messages
       ~t EXPR     messages addressed to EXPR
       ~T          tagged messages
       ~u          messages addressed to a subscribed mailing list (defined by subscribe commands)
       ~U          unread messages
       ~v          message is part of a collapsed thread.
       ~V          cryptographically verified messages
       ~x EXPR     messages which contain EXPR in the “References” or “In-Reply-To” field
       ~X MIN-MAX  messages with MIN - MAX attachments
       ~y EXPR     messages which contain EXPR in the “X-Label” field
       ~z MIN-MAX  messages with a size in the range MIN to MAX
       ~=          duplicated messages (see $duplicate_threads)
       ~$          unreferenced message (requires threaded view)
       ~(PATTERN)  messages  in  threads  containing  messages  matching  a  certain  pattern,  e.g. all threads
                   containing messages from you: ~(~P)
       ~<(PATTERN) messages whose immediate parent matches PATTERN, e.g. replies to your messages: ~<(~P)
       ~>(PATTERN) messages having an immediate child matching PATTERN, e.g. messages you replied to: ~>(~P)

       In the above, EXPR is a regular expression.

       With the ~d, ~m, ~n, ~r, ~X, and ~z operators, you can also specify ranges in the forms <MAX, >MIN, MIN-,
       and -MAX.

       With the ~z operator, the suffixes “K” and “M” are allowed to specify kilobyte and megabyte respectively.

   Matching dates
       The  ~d  and  ~r operators are used to match date ranges, which are interpreted to be given in your local
       time zone.

       A date is of the form DD[/MM[/[cc]YY]], that is, a two-digit date, optionally  followed  by  a  two-digit
       month,  optionally  followed  by  a year specifications.  Omitted fields default to the current month and
       year.

       Mutt understands either two or four digit year specifications.  When given a two-digit year, neomutt will
       interpret  values less than 70 as lying in the 21st century (i.e., “38” means 2038 and not 1938, and “00”
       is interpreted as 2000), and values greater than or equal to 70 as lying in the 20th century.

       Note that this behavior is Y2K compliant, but that neomutt does have a Y2.07K problem.

       If a date range consists of a single date, the operator in question will match that precise date.  If the
       date  range consists of a dash (“-”), followed by a date, this range will match any date before and up to
       the date given.  Similarly, a date followed by a dash matches the date given and any later point of time.
       Two dates, separated by a dash, match any date which lies in the given range of time.

       You  can  also  modify any absolute date by giving an error range.  An error range consists of one of the
       characters +, -, *, followed by a positive number, followed by one of the unit characters y, m, w, or  d,
       specifying  a  unit  of years, months, weeks, or days.  + increases the maximum date matched by the given
       interval of time, - decreases the minimum date matched by the given interval of time, and * increases the
       maximum  date  and  decreases  the minimum date matched by the given interval of time.  It is possible to
       give multiple error margins, which cumulate.  Example: 1/1/2001-1w+2w*3d

       You can also specify offsets relative to the current  date.   An  offset  is  specified  as  one  of  the
       characters  <, >, =, followed by a positive number, followed by one of the unit characters y, m, w, or d.
       > matches dates which are older than the specified amount of  time,  an  offset  which  begins  with  the
       character  <  matches  dates which are more recent than the specified amount of time, and an offset which
       begins with the character = matches points of time which are precisely the given amount of time ago.

CONFIGURATION VARIABLES

       abort_noattach
              Type: quadoption
              Default: no

              If  set  to  yes,  when  composing  messages  containing  the  regular  expression  specified   by
              attach_keyword  and  no  attachments  **  are  given,  composition  will be aborted. If set to no,
              composing ** messages as such will never be aborted.

              Example:

              set attach_keyword = "\\<attach(|ed|ments?)\\>"

       abort_nosubject
              Type: quadoption
              Default: ask-yes

              If set to yes, when composing messages and no subject is given at the subject prompt,  composition
              will  be  aborted.   If  set to no, composing messages with no subject given at the subject prompt
              will never be aborted.

       abort_unmodified
              Type: quadoption
              Default: yes

              If set to yes, composition will automatically abort after editing the message body if  no  changes
              are  made to the file (this check only happens after the first edit of the file).  When set to no,
              composition will never be aborted.

       alias_file
              Type: path
              Default: "~/.neomuttrc"

              The default file in which to save aliases created by the <create-alias> function. Entries added to
              this  file  are  encoded  in  the  character  set specified by $config_charset if it is set or the
              current character set otherwise.

              Note: NeoMutt will not automatically source this  file;  you  must  explicitly  use  the  “source”
              command for it to be executed in case this option points to a dedicated alias file.

              The  default  for  this  option is the currently used neomuttrc file, or “~/.neomuttrc” if no user
              neomuttrc was found.

       alias_format
              Type: string
              Default: "%4n %2f %t %-10a   %r"

              Specifies the format of the data displayed for the “alias” menu.   The  following  printf(3)-style
              sequences are available:
              %a     Alias name
              %f     Flags - currently, a “d” for an alias marked for deletion
              %n     Index number
              %r     Address which alias expands to
              %t     Character which indicates if the alias is tagged for inclusion

       allow_8bit
              Type: boolean
              Default: yes

              Controls  whether  8-bit  data  is  converted  to  7-bit  using either Quoted- Printable or Base64
              encoding when sending mail.

       allow_ansi
              Type: boolean
              Default: no

              Controls whether ANSI color codes in messages (and color tags in rich text  messages)  are  to  be
              interpreted.  Messages containing these codes are rare, but if this option is set, their text will
              be colored accordingly. Note that this may  override  your  color  choices,  and  even  present  a
              security problem, since a message could include a line like

              [-- PGP output follows ...

              and give it the same color as your attachment color (see also $crypt_timestamp).

       arrow_cursor
              Type: boolean
              Default: no

              When  set,  an  arrow  (“->”)  will  be  used  to  indicate  the current entry in menus instead of
              highlighting the whole line.  On slow network or  modem  links  this  will  make  response  faster
              because  there  is  less  that has to be redrawn on the screen when moving to the next or previous
              entries in the menu.

       ascii_chars
              Type: boolean
              Default: no

              If set, NeoMutt will use plain ASCII characters  when  displaying  thread  and  attachment  trees,
              instead of the default ACS characters.

       askbcc
              Type: boolean
              Default: no

              If  set, NeoMutt will prompt you for blind-carbon-copy (Bcc) recipients before editing an outgoing
              message.

       askcc
              Type: boolean
              Default: no

              If set, NeoMutt will prompt you for carbon-copy (Cc) recipients before  editing  the  body  of  an
              outgoing message.

       ask_follow_up
              Type: boolean
              Default: no

              If  set,  NeoMutt  will  prompt  you  for  follow-up groups before editing the body of an outgoing
              message.

       ask_x_comment_to
              Type: boolean
              Default: no

              If set, NeoMutt will prompt you for x-comment-to field before editing  the  body  of  an  outgoing
              message.

       assumed_charset
              Type: string
              Default: ""

              This  variable  is  a  colon-separated  list  of  character  encoding schemes for messages without
              character encoding indication.  Header field values and message  body  content  without  character
              encoding  indication  would be assumed that they are written in one of this list.  By default, all
              the header fields and message body without any charset indication are assumed to be in “us-ascii”.

              For example, Japanese users might prefer this:

              set assumed_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"

              However, only the first content is valid for the message body.

       attach_charset
              Type: string
              Default: ""

              This variable is a colon-separated list of character encoding schemes for text  file  attachments.
              NeoMutt  uses  this setting to guess which encoding files being attached are encoded in to convert
              them to a proper character set given in $send_charset.

              If unset, the value of $charset will be used instead.  For example,  the  following  configuration
              would work for Japanese text handling:

              set attach_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"

              Note:  for  Japanese  users,  “iso-2022-*”  must be put at the head of the value as shown above if
              included.

       attach_format
              Type: string
              Default: "%u%D%I %t%4n %T%.40d%> [%.7m/%.10M, %.6e%?C?, %C?, %s] "

              This variable describes the format  of  the  “attachment”  menu.   The  following  printf(3)-style
              sequences are understood:
              %C     Charset
              %c     Requires charset conversion (“n” or “c”)
              %D     Deleted flag
              %d     Description (if none, falls back to %F)
              %e     MIME content-transfer-encoding
              %f     Filename
              %F     Filename in content-disposition header (if none, falls back to %f)
              %I     Disposition (“I” for inline, “A” for attachment)
              %m     Major MIME type
              %M     MIME subtype
              %n     Attachment number
              %Q     “Q”, if MIME part qualifies for attachment counting
              %s     Size
              %T     Graphic tree characters
              %t     Tagged flag
              %u     Unlink (=to delete) flag
              %X     Number of qualifying MIME parts in this part and its children (please see the “attachments”
                     section for possible speed effects)
              %>X    Right justify the rest of the string and pad with character “X”
              %|X    Pad to the end of the line with character “X”
              %*X    Soft-fill with character “X” as pad

              For an explanation of “soft-fill”, see the $index_format documentation.

       attach_keyword
              Type: regular expression
              Default: "\<(attach|attached|attachments?)\>"

              If abort_noattach is not set to no, then the body of the message will be scanned for this  regular
              expression, and if found, you will be prompted if there are no attachments.

       attach_sep
              Type: string
              Default: "\n"

              The  separator to add between attachments when operating (saving, printing, piping, etc) on a list
              of tagged attachments.

       attach_split
              Type: boolean
              Default: yes

              If this variable is unset, when operating (saving, printing, piping, etc)  on  a  list  of  tagged
              attachments,  NeoMutt  will  concatenate  the  attachments  and  will  operate on them as a single
              attachment. The $attach_sep separator is added after  each  attachment.  When  set,  NeoMutt  will
              operate on the attachments one by one.

       attribution
              Type: string
              Default: "On %d, %n wrote:"

              This  is  the  string  that will precede a message which has been included in a reply.  For a full
              listing of defined printf(3)-like sequences see the section on $index_format.

       attribution_locale
              Type: string
              Default: ""

              The locale used by strftime(3) to format dates in the attribution string.  Legal  values  are  the
              strings your system accepts for the locale environment variable $LC_TIME.

              This  variable  is  to  allow  the attribution date format to be customized by recipient or folder
              using hooks.  By default, NeoMutt will use your locale environment, so there is  no  need  to  set
              this except to override that default.

       auto_tag
              Type: boolean
              Default: no

              When  set,  functions  in  the  index  menu  which  affect a message will be applied to all tagged
              messages (if there are any).  When unset, you must first use the <tag-prefix> function  (bound  to
              “;” by default) to make the next function apply to all tagged messages.

       autoedit
              Type: boolean
              Default: no

              When  set along with $edit_headers, NeoMutt will skip the initial send-menu (prompting for subject
              and recipients) and allow you to  immediately  begin  editing  the  body  of  your  message.   The
              send-menu may still be accessed once you have finished editing the body of your message.

              Note:  when  this  option  is  set,  you  cannot use send-hooks that depend on the recipients when
              composing a new (non-reply) message, as the initial list of recipients is empty.

              Also see $fast_reply.

       beep
              Type: boolean
              Default: yes

              When this variable is set, NeoMutt will beep when an error occurs.

       beep_new
              Type: boolean
              Default: no

              When this variable is set, NeoMutt will beep whenever it prints a message  notifying  you  of  new
              mail.  This is independent of the setting of the $beep variable.

       bounce
              Type: quadoption
              Default: ask-yes

              Controls  whether  you  will  be  asked to confirm bouncing messages.  If set to yes you don't get
              asked if you want to bounce a message. Setting this variable to no is not  generally  useful,  and
              thus not recommended, because you are unable to bounce messages.

       bounce_delivered
              Type: boolean
              Default: yes

              When  this  variable  is  set,  NeoMutt  will include Delivered-To headers when bouncing messages.
              Postfix users may wish to unset this variable.

              Note: On Debian systems, this option is unset by default in /etc/Muttrc.

       braille_friendly
              Type: boolean
              Default: no

              When this variable is set, NeoMutt will place the cursor at the beginning of the current  line  in
              menus,  even  when  the  $arrow_cursor variable is unset, making it easier for blind persons using
              Braille displays to follow these menus.  The option  is  unset  by  default  because  many  visual
              terminals don't permit making the cursor invisible.

       catchup_newsgroup
              Type: quadoption
              Default: ask-yes

              If  this  variable  is  set, NeoMutt will mark all articles in newsgroup as read when you quit the
              newsgroup (catchup newsgroup).

       certificate_file
              Type: path
              Default: "~/.mutt_certificates"

              This variable specifies the file where the certificates you  trust  are  saved.  When  an  unknown
              certificate  is  encountered,  you  are  asked  if  you  accept  it  or not. If you accept it, the
              certificate can also be saved in this file and further connections are automatically accepted.

              You can also manually add CA certificates in this file. Any server certificate that is signed with
              one of these CA certificates is also automatically accepted.

              Example:

              set certificate_file=~/.neomutt/certificates

       change_folder_next
              Type: boolean
              Default: no

              When  this variable is set, the <change-folder> function mailbox suggestion will start at the next
              folder in your “mailboxes” list, instead of starting at the first folder in the list.

       charset
              Type: string
              Default: ""

              Character set your terminal uses to display and enter textual data.  It is also the  fallback  for
              $send_charset.

              Upon  startup  NeoMutt  tries to derive this value from environment variables such as $LC_CTYPE or
              $LANG.

              Note: It should only be set in case NeoMutt  isn't  able  to  determine  the  character  set  used
              correctly.

       check_mbox_size
              Type: boolean
              Default: no

              When  this  variable  is  set,  NeoMutt  will  use file size attribute instead of access time when
              checking for new mail in mbox and mmdf folders.

              This variable is unset by default and should only be enabled when new  mail  detection  for  these
              folder types is unreliable or doesn't work.

              Note  that  enabling  this  variable  should  happen  before  any  “mailboxes” directives occur in
              configuration files regarding mbox or mmdf folders because NeoMutt needs to determine the  initial
              new  mail  status  of  such  a  mailbox  by  performing  a  fast  mailbox scan when it is defined.
              Afterwards the new mail status is tracked by file size changes.

       check_new
              Type: boolean
              Default: yes

              Note: this option only affects maildir and MH style mailboxes.

              When set, NeoMutt will check for new mail delivered while the mailbox is open.  Especially with MH
              mailboxes,  this  operation  can take quite some time since it involves scanning the directory and
              checking each file to see if it has already been looked at.  If this variable is unset,  no  check
              for new mail is performed while the mailbox is open.

       collapse_unread
              Type: boolean
              Default: yes

              When unset, NeoMutt will not collapse a thread if it contains any unread messages.

       collapse_flagged
              Type: boolean
              Default: yes

              When unset, NeoMutt will not collapse a thread if it contains any flagged messages.

       compose_format
              Type: string
              Default: "-- NeoMutt: Compose  [Approx. msg size: %l   Atts: %a]%>-"

              Controls the format of the status line displayed in the “compose” menu.  This string is similar to
              $status_format, but has its own set of printf(3)-like sequences:
              %a     Total number of attachments
              %h     Local hostname
              %l     Approximate size (in bytes) of the current message
              %v     NeoMutt version string

              See  the  text  describing  the  $status_format  option  for  more  information  on  how  to   set
              $compose_format.

       config_charset
              Type: string
              Default: ""

              When defined, NeoMutt will recode commands in rc files from this encoding to the current character
              set as specified by $charset and aliases written to $alias_file from the current character set.

              Please note that if setting $charset it must be done before setting $config_charset.

              Recoding should be avoided as it may render unconvertable characters as question marks  which  can
              lead to undesired side effects (for example in regular expressions).

       confirmappend
              Type: boolean
              Default: yes

              When set, NeoMutt will prompt for confirmation when appending messages to an existing mailbox.

       confirmcreate
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will prompt for confirmation when saving messages to a mailbox which does not
              yet exist before creating it.

       connect_timeout
              Type: number
              Default: 30

              Causes NeoMutt to timeout a network connection (for IMAP, POP or SMTP) after this many seconds  if
              the  connection  is  not  able  to  be  established.   A  negative  value  causes  NeoMutt to wait
              indefinitely for the connection attempt to succeed.

       content_type
              Type: string
              Default: "text/plain"

              Sets the default Content-Type for the body of newly composed messages.

       copy
              Type: quadoption
              Default: yes

              This variable controls whether or not copies of your outgoing messages will  be  saved  for  later
              references.  Also see $record, $save_name, $force_name and “fcc-hook”.

       crypt_autoencrypt
              Type: boolean
              Default: no

              Setting this variable will cause NeoMutt to always attempt to PGP encrypt outgoing messages.  This
              is probably only useful in connection to the “send-hook” command.  It can be overridden by use  of
              the   pgp   menu,  when  encryption  is  not  required  or  signing  is  requested  as  well.   If
              $smime_is_default is set, then OpenSSL is used instead to create S/MIME messages and settings  can
              be overridden by use of the smime menu instead.  (Crypto only)

       crypt_autopgp
              Type: boolean
              Default: yes

              This  variable controls whether or not NeoMutt may automatically enable PGP encryption/signing for
              messages.  See also $crypt_autoencrypt, $crypt_replyencrypt, $crypt_autosign, $crypt_replysign and
              $smime_is_default.

       crypt_autosign
              Type: boolean
              Default: no

              Setting  this  variable  will  cause  NeoMutt to always attempt to cryptographically sign outgoing
              messages.  This can be overridden by use of  the  pgp  menu,  when  signing  is  not  required  or
              encryption  is  requested  as  well.  If $smime_is_default is set, then OpenSSL is used instead to
              create S/MIME messages and settings can be overridden by use of the smime menu instead of the  pgp
              menu.  (Crypto only)

       crypt_autosmime
              Type: boolean
              Default: yes

              This  variable  controls whether or not NeoMutt may automatically enable S/MIME encryption/signing
              for messages. See also $crypt_autoencrypt, $crypt_replyencrypt, $crypt_autosign,  $crypt_replysign
              and $smime_is_default.

       crypt_confirmhook
              Type: boolean
              Default: yes

              If  set, then you will be prompted for confirmation of keys when using the crypt-hook command.  If
              unset, no such confirmation prompt will  be  presented.   This  is  generally  considered  unsafe,
              especially where typos are concerned.

       crypt_opportunistic_encrypt
              Type: boolean
              Default: no

              Setting  this variable will cause NeoMutt to automatically enable and disable encryption, based on
              whether all message recipient keys can be located by NeoMutt.

              When this option is enabled, NeoMutt will enable/disable encryption each time the TO, CC, and  BCC
              lists  are  edited.   If  $edit_headers  is  set, NeoMutt will also do so each time the message is
              edited.

              While this is set, encryption can't be manually enabled/disabled.  The pgp or smime menus  provide
              a selection to temporarily disable this option for the current message.

              If  $crypt_autoencrypt or $crypt_replyencrypt enable encryption for a message, this option will be
              disabled for that message.  It can be manually re-enabled in the  pgp  or  smime  menus.   (Crypto
              only)

       crypt_replyencrypt
              Type: boolean
              Default: yes

              If  set,  automatically  PGP  or OpenSSL encrypt replies to messages which are encrypted.  (Crypto
              only)

       crypt_replysign
              Type: boolean
              Default: no

              If set, automatically PGP or OpenSSL sign replies to messages which are signed.

              Note: this does not work on messages that are encrypted and signed!  (Crypto only)

       crypt_replysignencrypted
              Type: boolean
              Default: no

              If set, automatically PGP or OpenSSL sign replies to messages  which  are  encrypted.  This  makes
              sense  in  combination  with $crypt_replyencrypt, because it allows you to sign all messages which
              are automatically encrypted.  This works  around  the  problem  noted  in  $crypt_replysign,  that
              NeoMutt is not able to find out whether an encrypted message is also signed.  (Crypto only)

       crypt_timestamp
              Type: boolean
              Default: yes

              If  set,  NeoMutt  will  include  a  time  stamp in the lines surrounding PGP or S/MIME output, so
              spoofing such lines is more difficult.  If you are using colors to mark these lines, and  rely  on
              these, you may unset this setting.  (Crypto only)

       crypt_use_gpgme
              Type: boolean
              Default: no

              This variable controls the use of the GPGME-enabled crypto backends.  If it is set and NeoMutt was
              built with gpgme support, the gpgme code for S/MIME and PGP will be used instead  of  the  classic
              code.   Note  that  you  need to set this option in .neomuttrc; it won't have any effect when used
              interactively.

              Note that the GPGME backend does not support creating old-style inline (traditional) PGP encrypted
              or signed messages (see $pgp_autoinline).

       crypt_use_pka
              Type: boolean
              Default: no

              Controls   whether  NeoMutt  uses  PKA  (see  http://www.g10code.de/docs/pka-intro.de.pdf)  during
              signature verification (only supported by the GPGME backend).

       crypt_verify_sig
              Type: quadoption
              Default: yes

              If “yes”, always attempt to verify PGP or S/MIME signatures.  If “ask-*”, ask whether  or  not  to
              verify the signature.  If “no”, never attempt to verify cryptographic signatures.  (Crypto only)

       date_format
              Type: string
              Default: "!%a, %b %d, %Y at %I:%M:%S%p %Z"

              This variable controls the format of the date printed by the “%d” sequence in $index_format.  This
              is passed to the strftime(3) function to process the date, see the man page for the proper syntax.

              Unless the first character in the string is a bang  (“!”),  the  month  and  week  day  names  are
              expanded  according  to  the  locale.  If the first character in the string is a bang, the bang is
              discarded, and the month and week day names in the rest of the string are expanded in the C locale
              (that is in US English).

       debug_level
              Type: number
              Default: 0

              The  debug  level.  Note: to debug the early startup process (before the configuration is loaded),
              “-d” neomutt argument must be used.  debug_level/debug_file are ignored until it's read  from  the
              configuration file.

       debug_file
              Type: path
              Default: "~/.neomuttdebug"

              The  location  prefix of the debug file, 0 is append to the debug file Old debug files are renamed
              with the prefix 1, 2, 3 and 4.  See “debug_level” for more detail.

       default_hook
              Type: string
              Default: "~f %s !~P | (~P ~C %s)"

              This variable controls how “message-hook”, “reply-hook”, “send-hook”,  “send2-hook”,  “save-hook”,
              and  “fcc-hook”  will  be interpreted if they are specified with only a simple regex, instead of a
              matching pattern.  The hooks are expanded when they are declared, so a hook  will  be  interpreted
              according to the value of this variable at the time the hook is declared.

              The  default  value  matches  if the message is either from a user matching the regular expression
              given, or if it is from you (if the from address matches “alternates”) and is to  or  cc'ed  to  a
              user matching the given regular expression.

       delete
              Type: quadoption
              Default: ask-yes

              Controls  whether  or not messages are really deleted when closing or synchronizing a mailbox.  If
              set to yes, messages marked for deleting will automatically be purged without prompting.   If  set
              to no, messages marked for deletion will be kept in the mailbox.

       delete_untag
              Type: boolean
              Default: yes

              If  this  option is set, NeoMutt will untag messages when marking them for deletion.  This applies
              when you either explicitly delete a message, or when you save it to another folder.

       digest_collapse
              Type: boolean
              Default: yes

              If this option is  set,  NeoMutt's  received-attachments  menu  will  not  show  the  subparts  of
              individual messages in a multipart/digest.  To see these subparts, press “v” on that menu.

       display_filter
              Type: path
              Default: ""

              When  set,  specifies a command used to filter messages.  When a message is viewed it is passed as
              standard input to $display_filter, and the filtered message is read from the standard output.

              When preparing the message, NeoMutt inserts some escape sequences into the text.  They are of  the
              form: <esc>]9;XXX<bel> where "XXX" is a random 64-bit number.

              If  these  escape  sequences  interfere  with  your  filter, they can be removed using a tool like
              ansifilter or sed 's/^\x1b]9;[0-9]\+\x7//'

              If they are removed, then PGP and MIME headers will no longer be coloured.  This can be  fixed  by
              adding this to your config: color body magenta default '^\[-- .* --\]$'.

       dsn_notify
              Type: string
              Default: ""

              This  variable sets the request for when notification is returned.  The string consists of a comma
              separated list (no spaces!) of one or more of the following: never, to never request notification,
              failure, to request notification on transmission failure, delay, to be notified of message delays,
              success, to be notified of successful transmission.

              Example:

              set dsn_notify="failure,delay"

              Note: when using $sendmail for delivery, you should not enable this unless you  are  either  using
              Sendmail  8.8.x or greater or a MTA providing a sendmail(1)-compatible interface supporting the -N
              option for DSN. For SMTP delivery, DSN support is auto-detected so that it depends on  the  server
              whether DSN will be used or not.

       dsn_return
              Type: string
              Default: ""

              This  variable  controls  how  much of your message is returned in DSN messages.  It may be set to
              either hdrs to return just the message header, or full to return the full message.

              Example:

              set dsn_return=hdrs

              Note: when using $sendmail for delivery, you should not enable this unless you  are  either  using
              Sendmail  8.8.x or greater or a MTA providing a sendmail(1)-compatible interface supporting the -R
              option for DSN. For SMTP delivery, DSN support is auto-detected so that it depends on  the  server
              whether DSN will be used or not.

       duplicate_threads
              Type: boolean
              Default: yes

              This  variable  controls  whether NeoMutt, when $sort is set to threads, threads messages with the
              same Message-Id together.  If it is set, it will indicate that it thinks they  are  duplicates  of
              each other with an equals sign in the thread tree.

       edit_headers
              Type: boolean
              Default: no

              This  option  allows  you to edit the header of your outgoing messages along with the body of your
              message.

              Although the compose menu may have localized header labels, the labels passed to your editor  will
              be standard RFC2822 headers, (e.g. To:, Cc:, Subject:).  Headers added in your editor must also be
              RFC2822 headers, or one  of  the  pseudo  headers  listed  in  “edit-header”.   NeoMutt  will  not
              understand localized header labels, just as it would not when parsing an actual email.

              Note  that  changes  made  to  the  References: and Date: headers are ignored for interoperability
              reasons.

       editor
              Type: path
              Default: ""

              This variable specifies which editor is used by NeoMutt.  It defaults to the value of the $VISUAL,
              or $EDITOR, environment variable, or to the string “/usr/bin/editor” if neither of those are set.

              The  $editor  string may contain a %s escape, which will be replaced by the name of the file to be
              edited.  If the %s escape does not appear in $editor, a space  and  the  name  to  be  edited  are
              appended.

              The resulting string is then executed by running

              sh -c 'string'

              where string is the expansion of $editor described above.

       empty_subject
              Type: string
              Default: "Re: your mail"

              This  variable  specifies  the subject to be used when replying to an email with an empty subject.
              It defaults to "Re: your mail".

       encode_from
              Type: boolean
              Default: no

              When set, NeoMutt will quoted-printable encode messages when they contain the string “From ” (note
              the  trailing  space)  in  the beginning of a line.  This is useful to avoid the tampering certain
              mail delivery and transport agents tend to do with  messages  (in  order  to  prevent  tools  from
              misinterpreting the line as a mbox message separator).

       envelope_from_address
              Type: e-mail address
              Default: ""

              Manually   sets   the   envelope   sender  for  outgoing  messages.   This  value  is  ignored  if
              $use_envelope_from is unset.

       escape
              Type: string
              Default: "~"

              Escape character to use for functions in the built-in editor.

       fast_reply
              Type: boolean
              Default: no

              When set, the initial prompt for recipients and subject are skipped when replying to messages, and
              the initial prompt for subject is skipped when forwarding messages.

              Note: this variable has no effect when the $autoedit variable is set.

       fcc_attach
              Type: quadoption
              Default: yes

              This  variable  controls  whether or not attachments on outgoing messages are saved along with the
              main body of your message.

       fcc_clear
              Type: boolean
              Default: no

              When this variable is set, FCCs will be stored unencrypted and  unsigned,  even  when  the  actual
              message is encrypted and/or signed.  (PGP only)

       flag_safe
              Type: boolean
              Default: no

              If set, flagged messages cannot be deleted.

       folder
              Type: path
              Default: "~/Mail"

              Specifies  the  default  location  of your mailboxes.  A “+” or “=” at the beginning of a pathname
              will be expanded to the value of this variable.  Note that if you change this variable  (from  the
              default)  value you need to make sure that the assignment occurs before you use “+” or “=” for any
              other variables since expansion takes place when handling the “mailboxes” command.

       folder_format
              Type: string
              Default: "%2C %t %N %F %2l %-8.8u %-8.8g %8s %d %f"

              This variable allows you to customize the file browser  display  to  your  personal  taste.   This
              string is similar to $index_format, but has its own set of printf(3)-like sequences:
              %C     Current file number
              %d     Date/time folder was last modified
              %D     Date/time folder was last modified using $date_format.
              %f     Filename  (“/”  is appended to directory names, “@” to symbolic links and “*” to executable
                     files)
              %F     File permissions
              %g     Group name (or numeric gid, if missing)
              %l     Number of hard links
              %m     Number of messages in the mailbox *
              %n     Number of unread messages in the mailbox *
              %N     “N” if mailbox has new mail, blank otherwise
              %s     Size in bytes
              %t     “*” if the file is tagged, blank otherwise
              %u     Owner name (or numeric uid, if missing)
              %>X    Right justify the rest of the string and pad with character “X”
              %|X    Pad to the end of the line with character “X”
              %*X    Soft-fill with character “X” as pad

              For an explanation of “soft-fill”, see the $index_format documentation.

              * = can be optionally printed if nonzero

              %m, %n, and %N only work for monitored mailboxes.  %m requires $mail_check_stats to  be  set.   %n
              requires $mail_check_stats to be set (except for IMAP mailboxes).

       followup_to
              Type: boolean
              Default: yes

              Controls whether or not the “Mail-Followup-To:” header field is generated when sending mail.  When
              set, NeoMutt will generate this field when you are replying to a  known  mailing  list,  specified
              with the “subscribe” or “lists” commands.

              This  field has two purposes.  First, preventing you from receiving duplicate copies of replies to
              messages which you send to mailing lists, and second, ensuring that you do get a reply  separately
              for any messages sent to known lists to which you are not subscribed.

              The  header  will  contain only the list's address for subscribed lists, and both the list address
              and your own email address for unsubscribed lists.  Without this header, a  group  reply  to  your
              message sent to a subscribed list will be sent to both the list and your address, resulting in two
              copies of the same email for you.

       followup_to_poster
              Type: quadoption
              Default: ask-yes

              If this variable is set and the keyword "poster" is present in Followup-To  header,  follow-up  to
              newsgroup  function  is not permitted.  The message will be mailed to the submitter of the message
              via mail.

       force_name
              Type: boolean
              Default: no

              This variable is similar to $save_name, except that NeoMutt will store a  copy  of  your  outgoing
              message by the username of the address you are sending to even if that mailbox does not exist.

              Also see the $record variable.

       forward_attribution_intro
              Type: string
              Default: "----- Forwarded message from %f -----"

              This  is  the  string  that  will precede a message which has been forwarded in the main body of a
              message (when $mime_forward is unset).  For a full listing of defined printf(3)-like sequences see
              the section on $index_format.  See also $attribution_locale.

       forward_attribution_trailer
              Type: string
              Default: "----- End forwarded message -----"

              This  is  the  string  that  will  follow a message which has been forwarded in the main body of a
              message (when $mime_forward is unset).  For a full listing of defined printf(3)-like sequences see
              the section on $index_format.  See also $attribution_locale.

       forward_decode
              Type: boolean
              Default: yes

              Controls  the  decoding  of  complex MIME messages into text/plain when forwarding a message.  The
              message header is also RFC2047 decoded.  This variable is only used, if  $mime_forward  is  unset,
              otherwise $mime_forward_decode is used instead.

       forward_decrypt
              Type: boolean
              Default: yes

              Controls  the handling of encrypted messages when forwarding a message.  When set, the outer layer
              of encryption is  stripped  off.   This  variable  is  only  used  if  $mime_forward  is  set  and
              $mime_forward_decode is unset.  (PGP only)

       forward_edit
              Type: quadoption
              Default: yes

              This  quadoption  controls  whether  or  not  the  user is automatically placed in the editor when
              forwarding messages.  For those who always want to forward with no modification, use a setting  of
              “no”.

       forward_format
              Type: string
              Default: "[%a: %s]"

              This  variable  controls  the  default subject when forwarding a message.  It uses the same format
              sequences as the $index_format variable.

       forward_quote
              Type: boolean
              Default: no

              When set, forwarded messages included in the main body  of  the  message  (when  $mime_forward  is
              unset) will be quoted using $indent_string.

       forward_references
              Type: boolean
              Default: no

              When  set,  forwarded messages set the “In-Reply-To:” and “References:” headers in the same way as
              normal replies would. Hence the forwarded message becomes part of the original thread  instead  of
              starting a new one.

       from
              Type: e-mail address
              Default: ""

              When  set,  this  variable  contains  a default from address.  It can be overridden using “my_hdr”
              (including from a “send-hook”) and $reverse_name.  This variable is ignored if $use_from is unset.

              This setting defaults to the contents of the environment variable $EMAIL.

       from_chars
              Type: string
              Default: ""

              Controls the character used to prefix the %F and %L fields in the index.
              Character
                     Description
              1      Mail is written by you and has a To address, or has a known mailing list in the To address.
              2      Mail is written by you and has a Cc address, or has a known mailing list in the Cc address.
              3      Mail is written by you and has a Bcc address.
              4      All remaining cases.

              If this is empty or unset (default), the traditional long "To ", "Cc " and  "Bcc  "  prefixes  are
              used.   If  set but too short to include a character for a particular case, a single space will be
              prepended to the field.  To prevent any prefix at all from being added in a particular  case,  use
              the special value CR (aka ^M) for the corresponding character.

              This  slightly odd interface is necessitated by NeoMutt's handling of string variables; one cannot
              tell a variable that is unset from one that is set to the empty string.

       gecos_mask
              Type: regular expression
              Default: "^[^,]*"

              A regular expression used by NeoMutt to parse the GECOS field of a password entry  when  expanding
              the  alias.   The  default  value  will return the string up to the first “,” encountered.  If the
              GECOS field contains a string like “lastname, firstname” then you should set it to “.*”.

              This can be useful if you see the following behavior: you address an e-mail to  user  ID  “stevef”
              whose  full  name is “Steve Franklin”.  If NeoMutt expands “stevef” to “"Franklin" stevef@foo.bar”
              then you should set the $gecos_mask to a regular expression that will  match  the  whole  name  so
              NeoMutt will expand “Franklin” to “Franklin, Steve”.

       group_index_format
              Type: string
              Default: "%4C %M%N %5s  %-45.45f %d"

              This  variable allows you to customize the newsgroup browser display to your personal taste.  This
              string is similar to “index_format”, but has its own set of printf()-like sequences:
              %C     Current newsgroup number
              %d     Description of newsgroup (becomes from server)
              %f     Newsgroup name
              %M     - if newsgroup not allowed for direct post (moderated for example)
              %N     N if newsgroup is new, u if unsubscribed, blank otherwise
              %n     Number of new articles in newsgroup
              %s     Number of unread articles in newsgroup
              %>X    Right justify the rest of the string and pad with character "X"
              %|X    Pad to the end of the line with character "X"

       hdrs
              Type: boolean
              Default: yes

              When unset, the header fields normally added by  the  “my_hdr”  command  are  not  created.   This
              variable  must  be  unset  before composing a new message or replying in order to take effect.  If
              set, the user defined header fields are added to every new message.

       header
              Type: boolean
              Default: no

              When set, this variable causes NeoMutt to include the header of the message you  are  replying  to
              into the edit buffer.  The $weed setting applies.

       header_cache
              Type: path
              Default: ""

              This  variable  points  to  the  header  cache  database.  If pointing to a directory NeoMutt will
              contain a header cache database file per folder, if pointing to a file that file will be a  single
              global header cache. By default it is unset so no header caching will be used.

              Header  caching  can  greatly  improve  speed  when  opening  POP, IMAP MH or Maildir folders, see
              “caching” for details.

       header_cache_backend
              Type: -none-
              Default: 0

              This variable specifies the header cache backend.

       header_cache_compress
              Type: boolean
              Default: yes

              When NeoMutt is compiled with qdbm, tokyocabinet or kyotocabinet as  header  cache  backend,  this
              option  determines  whether the database will be compressed. Compression results in database files
              roughly being one fifth of the usual diskspace, but the  decompression  can  result  in  a  slower
              opening  of  cached folder(s) which in general is still much faster than opening non header cached
              folders.

       header_color_partial
              Type: boolean
              Default: no

              When set, color header regexes behave like color body regexes: color is applied to the exact  text
              matched by the regex.  When unset, color is applied to the entire header.

              One use of this option might be to apply color to just the header labels.

              See “color” for more details.

       help
              Type: boolean
              Default: yes

              When  set,  help  lines  describing the bindings for the major functions provided by each menu are
              displayed on the first line of the screen.

              Note: The binding will not be displayed correctly if the function is bound to  a  sequence  rather
              than  a  single  keystroke.   Also, the help line may not be updated if a binding is changed while
              NeoMutt is running.  Since this variable is primarily aimed at new users, neither of these  should
              present a major problem.

       hidden_host
              Type: boolean
              Default: no

              When  set,  NeoMutt will skip the host name part of $hostname variable when adding the domain part
              to addresses.  This variable does not affect the generation of Message-IDs, and it will  not  lead
              to the cut-off of first-level domains.

       hide_limited
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  not  show  the presence of messages that are hidden by limiting, in the
              thread tree.

       hide_missing
              Type: boolean
              Default: yes

              When set, NeoMutt will not show the presence of missing messages in the thread tree.

       hide_thread_subject
              Type: boolean
              Default: yes

              When set, NeoMutt will not show the subject of messages in the thread  tree  that  have  the  same
              subject as their parent or closest previously displayed sibling.

       hide_top_limited
              Type: boolean
              Default: no

              When  set,  NeoMutt will not show the presence of messages that are hidden by limiting, at the top
              of threads in the thread tree.  Note that when $hide_limited is set,  this  option  will  have  no
              effect.

       hide_top_missing
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  not  show the presence of missing messages at the top of threads in the
              thread tree.  Note that when $hide_missing is set, this option will have no effect.

       history
              Type: number
              Default: 10

              This variable controls the size (in number of strings remembered) of the string history buffer per
              category. The buffer is cleared each time the variable is set.

       history_file
              Type: path
              Default: "~/.mutthistory"

              The file in which NeoMutt will save its history.

              Also see $save_history.

       history_remove_dups
              Type: boolean
              Default: no

              When  set,  all  of  the  string history will be scanned for duplicates when a new entry is added.
              Duplicate entries in the $history_file will also be removed when it is periodically compacted.

       honor_disposition
              Type: boolean
              Default: no

              When set, NeoMutt will not display attachments with a disposition of “attachment” inline  even  if
              it  could  render  the part to plain text. These MIME parts can only be viewed from the attachment
              menu.

              If unset, NeoMutt will render all MIME parts it can properly transform to plain text.

       honor_followup_to
              Type: quadoption
              Default: yes

              This variable controls whether or not a Mail-Followup-To header is honored when group-replying  to
              a message.

       hostname
              Type: string
              Default: ""

              Specifies  the  fully-qualified hostname of the system NeoMutt is running on containing the host's
              name and the DNS domain it belongs to. It is used as the domain part (after “@”) for  local  email
              addresses as well as Message-Id headers.

              Its  value  is  determined  at  startup as follows: the node's hostname is first determined by the
              uname(3) function.  The domain is then looked  up  using  the  gethostname(2)  and  getaddrinfo(3)
              functions.  If those calls are unable to determine the domain, the full value returned by uname is
              used.  Optionally, NeoMutt can be compiled with a fixed domain name in which case a  detected  one
              is not used.

              Also see $use_domain and $hidden_host.

              Note:  On  Debian  systems, the default for this variable is obtained from /etc/mailname when Mutt
              starts.

       idn_decode
              Type: boolean
              Default: yes

              When set, NeoMutt will show you international domain names decoded.  Note: You can  use  IDNs  for
              addresses even if this is unset.  This variable only affects decoding. (IDN only)

       idn_encode
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  encode  international  domain names using IDN.  Unset this if your SMTP
              server can handle newer (RFC6531) UTF-8 encoded domains. (IDN only)

       ignore_linear_white_space
              Type: boolean
              Default: no

              This option replaces linear-white-space between encoded-word and text to a single space to prevent
              the display of MIME-encoded “Subject:” field from being divided into multiple lines.

       ignore_list_reply_to
              Type: boolean
              Default: no

              Affects  the  behavior  of  the  <reply> function when replying to messages from mailing lists (as
              defined by the “subscribe” or “lists” commands).  When set, if the “Reply-To:” field is set to the
              same  value  as the “To:” field, NeoMutt assumes that the “Reply-To:” field was set by the mailing
              list to automate responses to the list, and will ignore this field.  To direct a response  to  the
              mailing  list  when this option is set, use the <list-reply> function; <group-reply> will reply to
              both the sender and the list.

       show_multipart_alternative
              Type: string
              Default: ""

              When set to info, the multipart/alternative information is shown.  When set to inline, all of  the
              alternatives  are  displayed.   When  not  set,  the  default  behavior is to show only the chosen
              alternative.

       imap_authenticators
              Type: string
              Default: ""

              This is a colon-delimited list of authentication methods NeoMutt may attempt to use to log  in  to
              an  IMAP  server, in the order NeoMutt should try them.  Authentication methods are either “login”
              or the right side of  an  IMAP  “AUTH=xxx”  capability  string,  e.g.  “digest-md5”,  “gssapi”  or
              “cram-md5”.  This  option  is  case-insensitive.  If it's unset (the default) NeoMutt will try all
              available methods, in order from most-secure to least-secure.

              Example:

              set imap_authenticators="gssapi:cram-md5:login"

              Note: NeoMutt will only fall back to other authentication methods  if  the  previous  methods  are
              unavailable.  If  a  method is available but authentication fails, NeoMutt will not connect to the
              IMAP server.

       imap_check_subscribed
              Type: boolean
              Default: no

              When set, NeoMutt will fetch the set of subscribed folders from your server on connection, and add
              them  to  the  set  of  mailboxes  it  polls  for  new  mail  just as if you had issued individual
              “mailboxes” commands.

       imap_delim_chars
              Type: string
              Default: "/."

              This contains the list of characters which you would  like  to  treat  as  folder  separators  for
              displaying IMAP paths. In particular it helps in using the “=” shortcut for your folder variable.

       imap_headers
              Type: string
              Default: ""

              NeoMutt  requests  these  header  fields  in  addition  to  the default headers (“Date:”, “From:”,
              “Subject:”, “To:”, “Cc:”, “Message-Id:”, “References:”,  “Content-Type:”,  “Content-Description:”,
              “In-Reply-To:”,   “Reply-To:”,  “Lines:”,  “List-Post:”,  “X-Label:”)  from  IMAP  servers  before
              displaying the index menu. You may want to add more headers for spam detection.

              Note: This is a space separated list, items should be uppercase and not contain  the  colon,  e.g.
              “X-BOGOSITY X-SPAM-STATUS” for the “X-Bogosity:” and “X-Spam-Status:” header fields.

       imap_idle
              Type: boolean
              Default: no

              When set, NeoMutt will attempt to use the IMAP IDLE extension to check for new mail in the current
              mailbox. Some servers (dovecot was the inspiration for  this  option)  react  badly  to  NeoMutt's
              implementation. If your connection seems to freeze up periodically, try unsetting this.

       imap_keepalive
              Type: number
              Default: 300

              This  variable  specifies  the  maximum  amount  of  time in seconds that NeoMutt will wait before
              polling open IMAP connections, to prevent the server from closing them before NeoMutt has finished
              with them. The default is well within the RFC-specified minimum amount of time (30 minutes) before
              a server is allowed to do this, but in practice the RFC does get  violated  every  now  and  then.
              Reduce  this  number  if  you  find  yourself  getting  disconnected  from your IMAP server due to
              inactivity.

       imap_list_subscribed
              Type: boolean
              Default: no

              This variable configures whether IMAP folder browsing will look for only subscribed folders or all
              folders.  This can be toggled in the IMAP browser with the <toggle-subscribed> function.

       imap_login
              Type: string
              Default: ""

              Your login name on the IMAP server.

              This variable defaults to the value of $imap_user.

       imap_pass
              Type: string
              Default: ""

              Specifies the password for your IMAP account.  If unset, NeoMutt will prompt you for your password
              when you invoke the <imap-fetch-mail> function or try to open an IMAP folder.

              Warning: you should only use this option when you are on a  fairly  secure  machine,  because  the
              superuser can read your neomuttrc even if you are the only one who can read the file.

       imap_passive
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  not open new IMAP connections to check for new mail.  NeoMutt will only
              check for new mail over existing IMAP connections.  This  is  useful  if  you  don't  want  to  be
              prompted to user/password pairs on NeoMutt invocation, or if opening the connection is slow.

       imap_peek
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  avoid implicitly marking your mail as read whenever you fetch a message
              from the server. This is generally a good thing, but can make  closing  an  IMAP  folder  somewhat
              slower. This option exists to appease speed freaks.

       imap_pipeline_depth
              Type: number
              Default: 15

              Controls  the  number of IMAP commands that may be queued up before they are sent to the server. A
              deeper pipeline reduces the amount of time NeoMutt must wait for the server,  and  can  make  IMAP
              servers  feel much more responsive. But not all servers correctly handle pipelined commands, so if
              you have problems you might want to try setting this variable to 0.

              Note: Changes to this variable have no effect on open connections.

       imap_poll_timeout
              Type: number
              Default: 15

              This variable specifies the maximum amount of time  in  seconds  that  NeoMutt  will  wait  for  a
              response when polling IMAP connections for new mail, before timing out and closing the connection.
              Set to 0 to disable timing out.

       imap_servernoise
              Type: boolean
              Default: yes

              When set, NeoMutt will display warning messages from the IMAP  server  as  error  messages.  Since
              these  messages are often harmless, or generated due to configuration problems on the server which
              are out of the users' hands, you may wish to suppress them at some point.

       imap_user
              Type: string
              Default: ""

              The name of the user whose mail you intend to access on the IMAP server.

              This variable defaults to your user name on the local machine.

       implicit_autoview
              Type: boolean
              Default: no

              If set to “yes”, NeoMutt will look for a mailcap entry with the “copiousoutput” flag set for every
              MIME  attachment  it  doesn't  have  an  internal  viewer defined for.  If such an entry is found,
              NeoMutt will use the viewer defined in that entry to convert the body part to text form.

       include
              Type: quadoption
              Default: ask-yes

              Controls whether or not a copy of the message(s) you are replying to is included in your reply.

       include_onlyfirst
              Type: boolean
              Default: no

              Controls whether or not NeoMutt includes  only  the  first  attachment  of  the  message  you  are
              replying.

       indent_string
              Type: string
              Default: "> "

              Specifies  the  string  to  prepend  to  each  line  of  text quoted in a message to which you are
              replying.  You are strongly encouraged not to change this value, as it tends to agitate  the  more
              fanatical netizens.

              The  value  of  this  option  is  ignored if $text_flowed is set, because the quoting mechanism is
              strictly defined for format=flowed.

              This option is a format  string,  please  see  the  description  of  $index_format  for  supported
              printf(3)-style sequences.

       index_format
              Type: string
              Default: "%4C %Z %{%b %d} %-15.15L (%?l?%4l&%4c?) %s"

              This variable allows you to customize the message index display to your personal taste.

              “Format strings” are similar to the strings used in the C function printf(3) to format output (see
              the man page for more details).  For an explanation of the %?  construct,  see  the  status_format
              description.  The following sequences are defined in NeoMutt:
              %a     Address of the author
              %A     Reply-to address (if present; otherwise: address of author)
              %b     Filename of the original message folder (think mailbox)
              %B     The list to which the letter was sent, or else the folder name (%b).
              %c     Number of characters (bytes) in the message
              %C     Current message number
              %d     Date  and time of the message in the format specified by $date_format converted to sender's
                     time zone
              %D     Date and time of the message in the format specified by $date_format converted to the local
                     time zone
              %e     Current message number in thread
              %E     Number of messages in current thread
              %f     Sender (address + real name), either From: or Return-Path:
              %F     Author name, or recipient name if the message is from you
              %g     Newsgroup name (if compiled with NNTP support)
              %g     Message labels (e.g. notmuch tags)
              %H     Spam attribute(s) of this message
              %I     Initials of author
              %i     Message-id of the current message
              %K     The list to which the letter was sent (if any; otherwise: empty)
              %l     Number of lines in the message (does not work with maildir, Mh, and possibly IMAP folders)
              %L     If  an  address  in the “To:” or “Cc:” header field matches an address Defined by the users
                     “subscribe” command, this displays "To <list-name>", otherwise the same as %F
              %m     Total number of message in the mailbox
              %M     Number of hidden messages if the thread is collapsed
              %N     Message score
              %n     Author's real name (or address if missing)
              %O     Original save folder where NeoMutt would formerly have Stashed the message:  list  name  or
                     recipient name If not sent to a list
              %P     Progress indicator for the built-in pager (how much of the file has been displayed)
              %q     Newsgroup name (if compiled with NNTP support)
              %r     Comma separated list of “To:” recipients
              %R     Comma separated list of “Cc:” recipients
              %s     Subject of the message
              %S     Single character status of the message (“N”/“O”/“D”/“d”/“!”/“r”/“*”)
              %t     “To:” field (recipients)
              %T     The appropriate character from the $to_chars string
              %u     User (login) name of the author
              %v     First name of the author, or the recipient if the message is from you
              %W     Name of organization of author (“Organization:” field)
              %x     “X-Comment-To:” field (if present and compiled with NNTP support)
              %X     Number of attachments (please see the “attachments” section for possible speed effects)
              %y     “X-Label:” field, if present
              %Y     “X-Label:”  field,  if  present,  and (1) not at part of a thread tree, (2) at the top of a
                     thread, or (3) “X-Label:” is different from Preceding message's “X-Label:”
              %Z     A three character set of message status flags.  The  first  character  is  new/read/replied
                     flags    (“n”/“o”/“r”/“O”/“N”).     The    second    is   deleted   or   encryption   flags
                     (“D”/“d”/“S”/“P”/“s”/“K”).  The third is either tagged/flagged (“*”/“!”),  or  one  of  the
                     characters Listed in $to_chars.
              %zs    Message status flags
              %zc    Message crypto flags
              %zt    Message tag flags
              %{fmt} the  date and time of the message is converted to sender's time zone, and “fmt” is expanded
                     by the library function strftime(3); a leading bang disables locales
              %[fmt] the date and time of the message is converted to the local time zone, and “fmt” is expanded
                     by the library function strftime(3); a leading bang disables locales
              %(fmt) the  local  date  and time when the message was received.  “fmt” is expanded by the library
                     function strftime(3); a leading bang disables locales
              %>X    right justify the rest of the string and pad with character “X”
              %|X    pad to the end of the line with character “X”
              %*X    soft-fill with character “X” as pad

              Date format expressions can be constructed based on relative  dates.  Using  the  date  formatting
              operators  along  with  nested  conditionals,  the  date format can be modified based on how old a
              message is.  See the section on “Conditional Dates” for an explanation  and  examples  “Soft-fill”
              deserves  some  explanation:  Normal  right-justification will print everything to the left of the
              “%>”, displaying padding and whatever lies to  the  right  only  if  there's  room.  By  contrast,
              soft-fill  gives  priority  to  the  right-hand side, guaranteeing space to display it and showing
              padding only if there's still room. If necessary, soft-fill will eat text leftwards to  make  room
              for rightward text.

              Note that these expandos are supported in “save-hook”, “fcc-hook” and “fcc-save-hook”, too.

       inews
              Type: path
              Default: ""

              If  set,  specifies  the program and arguments used to deliver news posted by NeoMutt.  Otherwise,
              NeoMutt posts article using  current  connection  to  news  server.   The  following  printf-style
              sequence is understood:
              %a     account url
              %p     port
              %P     port if specified
              %s     news server name
              %S     url schema
              %u     username

              Example:

              set inews="/usr/local/bin/inews -hS"

       ispell
              Type: path
              Default: "ispell"

              How to invoke ispell (GNU's spell-checking software).

       keep_flagged
              Type: boolean
              Default: no

              If  set,  read  messages marked as flagged will not be moved from your spool mailbox to your $mbox
              mailbox, or as a result of a “mbox-hook” command.

       mail_check
              Type: number
              Default: 5

              This variable configures how often (in seconds) NeoMutt should look for new  mail.  Also  see  the
              $timeout variable.

       mail_check_recent
              Type: boolean
              Default: yes

              When  set,  NeoMutt will only notify you about new mail that has been received since the last time
              you opened the mailbox.  When unset, NeoMutt will notify  you  if  any  new  mail  exists  in  the
              mailbox, regardless of whether you have visited it recently.

              When  $mark_old  is  set,  NeoMutt  does  not consider the mailbox to contain new mail if only old
              messages exist.

       mail_check_stats
              Type: boolean
              Default: no

              When set, NeoMutt will periodically calculate message statistics of a mailbox  while  polling  for
              new mail.  It will check for unread, flagged, and total message counts.  Because this operation is
              more   performance   intensive,   it   defaults   to   unset,   and   has   a   separate   option,
              $mail_check_stats_interval, to control how often to update these counts.

       mail_check_stats_interval
              Type: number
              Default: 60

              When $mail_check_stats is set, this variable configures how often (in seconds) NeoMutt will update
              message counts.

       mailcap_path
              Type: string
              Default: ""

              This variable specifies which files to consult when attempting to display MIME bodies not directly
              supported by NeoMutt.

       mailcap_sanitize
              Type: boolean
              Default: yes

              If  set,  NeoMutt will restrict possible characters in mailcap % expandos to a well-defined set of
              safe characters.  This is the safe setting, but we  are  not  sure  it  doesn't  break  some  more
              advanced MIME stuff.

              DON'T CHANGE THIS SETTING UNLESS YOU ARE REALLY SURE WHAT YOU ARE DOING!

       maildir_header_cache_verify
              Type: boolean
              Default: yes

              Check  for  Maildir  unaware  programs  other  than NeoMutt having modified maildir files when the
              header cache is in use.  This incurs one stat(2) per message  every  time  the  folder  is  opened
              (which can be very slow for NFS folders).

       maildir_trash
              Type: boolean
              Default: no

              If  set,  messages  marked  as  deleted  will  be  saved  with the maildir trashed flag instead of
              unlinked.  Note: this only applies to maildir-style mailboxes.  Setting it will have no effect  on
              other mailbox types.

       maildir_check_cur
              Type: boolean
              Default: no

              If  set,  NeoMutt will poll both the new and cur directories of a maildir folder for new messages.
              This might be useful if other programs interacting with the folder (e.g. dovecot) are  moving  new
              messages  to  the  cur  directory.   Note  that  setting this option may slow down polling for new
              messages in large folders, since NeoMutt has to scan all cur messages.

       mark_macro_prefix
              Type: string
              Default: "'"

              Prefix  for  macros  created  using  mark-message.   A  new  macro  automatically  generated  with
              <mark-message>a will be composed from this prefix and the letter a.

       mark_old
              Type: boolean
              Default: yes

              Controls  whether  or  not  NeoMutt marks new unread messages as old if you exit a mailbox without
              reading them.  With this option set, the next time you start NeoMutt, the messages  will  show  up
              with an “O” next to them in the index menu, indicating that they are old.

       markers
              Type: boolean
              Default: yes

              Controls  the display of wrapped lines in the internal pager. If set, a “+” marker is displayed at
              the beginning of wrapped lines.

              Also see the $smart_wrap variable.

       mask
              Type: regular expression
              Default: "!^\.[^.]"

              A regular expression used in the file browser, optionally preceded by the not operator “!”.   Only
              files whose names match this mask will be shown. The match is always case-sensitive.

       mbox
              Type: path
              Default: "~/mbox"

              This specifies the folder into which read mail in your $spoolfile folder will be appended.

              Also see the $move variable.

       mbox_type
              Type: folder magic
              Default: mbox

              The  default  mailbox  type used when creating new folders. May be any of “mbox”, “MMDF”, “MH” and
              “Maildir”. This is overridden by the -m command-line option.

       menu_context
              Type: number
              Default: 0

              This variable controls the number of lines of context that are given when scrolling through menus.
              (Similar to $pager_context.)

       menu_move_off
              Type: boolean
              Default: yes

              When  unset,  the bottom entry of menus will never scroll up past the bottom of the screen, unless
              there are less entries than lines.  When set, the bottom entry may move off the bottom.

       menu_scroll
              Type: boolean
              Default: no

              When set, menus will be scrolled up or down one line when you attempt  to  move  across  a  screen
              boundary.   If unset, the screen is cleared and the next or previous page of the menu is displayed
              (useful for slow links to avoid many redraws).

       message_cache_clean
              Type: boolean
              Default: no

              If set, NeoMutt will clean out obsolete entries  from  the  message  cache  when  the  mailbox  is
              synchronized.  You  probably  only  want to set it every once in a while, since it can be a little
              slow (especially for large folders).

       message_cachedir
              Type: path
              Default: ""

              Set this to a directory and NeoMutt will cache copies of messages from your IMAP and  POP  servers
              here. You are free to remove entries at any time.

              When  setting  this variable to a directory, NeoMutt needs to fetch every remote message only once
              and can perform regular expression searches as fast as for local folders.

              Also see the $message_cache_clean variable.

       message_format
              Type: string
              Default: "%s"

              This is the string displayed in the “attachment” menu for attachments of type message/rfc822.  For
              a full listing of defined printf(3)-like sequences see the section on $index_format.

       meta_key
              Type: boolean
              Default: no

              If  set,  forces  NeoMutt to interpret keystrokes with the high bit (bit 8) set as if the user had
              pressed the Esc key and whatever key remains after having the high bit removed.  For  example,  if
              the  key  pressed  has an ASCII value of 0xf8, then this is treated as if the user had pressed Esc
              then “x”.  This is because the result of removing the high bit from 0xf8 is  0x78,  which  is  the
              ASCII character “x”.

       metoo
              Type: boolean
              Default: no

              If  unset,  NeoMutt  will  remove  your  address  (see  the “alternates” command) from the list of
              recipients when replying to a message.

       mh_purge
              Type: boolean
              Default: no

              When unset, NeoMutt will mimic mh's behavior and rename deleted messages to ,<old file name> in mh
              folders  instead  of  really  deleting  them.  This  leaves the message on disk but makes programs
              reading the folder ignore it. If the variable is set, the message files will simply be deleted.

              This option is similar to $maildir_trash for Maildir folders.

       mh_seq_flagged
              Type: string
              Default: "flagged"

              The name of the MH sequence used for flagged messages.

       mh_seq_replied
              Type: string
              Default: "replied"

              The name of the MH sequence used to tag replied messages.

       mh_seq_unseen
              Type: string
              Default: "unseen"

              The name of the MH sequence used for unseen messages.

       mime_forward
              Type: quadoption
              Default: no

              When set, the message you are forwarding will be attached as a separate message/rfc822  MIME  part
              instead  of included in the main body of the message.  This is useful for forwarding MIME messages
              so the receiver can properly view the message as it was delivered to you. If you  like  to  switch
              between MIME and not MIME from mail to mail, set this variable to “ask-no” or “ask-yes”.

              Also see $forward_decode and $mime_forward_decode.

       mime_forward_decode
              Type: boolean
              Default: no

              Controls  the  decoding  of  complex MIME messages into text/plain when forwarding a message while
              $mime_forward is set. Otherwise $forward_decode is used instead.

       mime_forward_rest
              Type: quadoption
              Default: yes

              When forwarding multiple attachments of a MIME message from the attachment menu, attachments which
              cannot  be  decoded  in a reasonable manner will be attached to the newly composed message if this
              option is set.

       mime_subject
              Type: boolean
              Default: yes

              If unset, 8-bit “subject:” line in article header will not be  encoded  according  to  RFC2047  to
              base64.   This  is  useful  when  message  is Usenet article, because MIME for news is nonstandard
              feature.

       mime_type_query_command
              Type: string
              Default: ""

              This specifies a command to run, to determine the mime type of a new attachment when  composing  a
              message.   Unless  $mime_type_query_first  is  set,  this  will  only  be  run if the attachment's
              extension is not found in the mime.types file.

              The string may contain a “%s”, which will be substituted with the  attachment  filename.   NeoMutt
              will  add  quotes  around the string substituted for “%s” automatically according to shell quoting
              rules, so you should avoid adding your own.  If no “%s” is  found  in  the  string,  NeoMutt  will
              append the attachment filename to the end of the string.

              The command should output a single line containing the attachment's mime type.

              Suggested values are “xdg-mime query filetype” or “file -bi”.

       mime_type_query_first
              Type: boolean
              Default: no

              When set, the $mime_type_query_command will be run before the mime.types lookup.

       mix_entry_format
              Type: string
              Default: "%4n %c %-16s %a"

              This  variable  describes  the  format of a remailer line on the mixmaster chain selection screen.
              The following printf(3)-like sequences are supported:
              %a     The remailer's e-mail address
              %c     Remailer capabilities
              %n     The running number on the menu
              %s     The remailer's short name

       mixmaster
              Type: path
              Default: "mixmaster"

              This variable contains the path to the Mixmaster binary on your system.  It is used  with  various
              sets  of  parameters  to gather the list of known remailers, and to finally send a message through
              the mixmaster chain.

              Note: On Debian systems, this option is set by default to “mixmaster-filter” in /etc/Muttrc.

       move
              Type: quadoption
              Default: no

              Controls whether or not NeoMutt will move read messages from your  spool  mailbox  to  your  $mbox
              mailbox, or as a result of a “mbox-hook” command.

       narrow_tree
              Type: boolean
              Default: no

              This  variable,  when  set,  makes the thread tree narrower, allowing deeper threads to fit on the
              screen.

       net_inc
              Type: number
              Default: 10

              Operations that expect to transfer a large amount of data  over  the  network  will  update  their
              progress every $net_inc kilobytes.  If set to 0, no progress messages will be displayed.

              See also $read_inc, $write_inc and $net_inc.

       new_mail_command
              Type: path
              Default: "NULL"

              If  set,  NeoMutt  will call this command after a new message is received.  See the $status_format
              documentation for the values that can be formatted into this command.

       news_cache_dir
              Type: path
              Default: "~/.neomutt"

              This variable pointing to directory where NeoMutt will save cached news articles and  headers  in.
              If  unset, articles and headers will not be saved at all and will be reloaded from the server each
              time.

       news_server
              Type: string
              Default: ""

              This variable specifies domain name or address of NNTP server. It  defaults  to  the  news  server
              specified  in  the environment variable $NNTPSERVER or contained in the file /etc/nntpserver.  You
              can also specify username and an alternative port for each news server, ie:

              [[s]news://][username[:password]@]server[:port]

       newsgroups_charset
              Type: string
              Default: "utf-8"

              Character set of newsgroups descriptions.

       newsrc
              Type: path
              Default: "~/.newsrc"

              The file, containing info about subscribed newsgroups - names and indexes of read  articles.   The
              following printf-style sequence is understood:
              %a     Account url
              %p     Port
              %P     Port if specified
              %s     News server name
              %S     Url schema
              %u     Username

       nntp_authenticators
              Type: string
              Default: ""

              This is a colon-delimited list of authentication methods NeoMutt may attempt to use to log in to a
              news server, in the order NeoMutt should try them.  Authentication methods are  either  “user”  or
              any  SASL  mechanism, e.g. “digest-md5”, “gssapi” or “cram-md5”.  This option is case-insensitive.
              If it's unset (the default) NeoMutt will try all available methods, in order from  most-secure  to
              least-secure.

              Example:

              set nntp_authenticators="digest-md5:user"

              Note:  NeoMutt  will  only  fall  back to other authentication methods if the previous methods are
              unavailable. If a method is available but authentication fails, NeoMutt will not  connect  to  the
              IMAP server.

       nntp_context
              Type: number
              Default: 1000

              This variable defines number of articles which will be in index when newsgroup entered.  If active
              newsgroup have more articles than this number, oldest articles will be ignored.  Also controls how
              many articles headers will be saved in cache when you quit newsgroup.

       nntp_listgroup
              Type: boolean
              Default: yes

              This  variable  controls  whether  or  not  existence of each article is checked when newsgroup is
              entered.

       nntp_load_description
              Type: boolean
              Default: yes

              This variable controls whether or  not  descriptions  for  each  newsgroup  must  be  loaded  when
              newsgroup is added to list (first time list loading or new newsgroup adding).

       nntp_user
              Type: string
              Default: ""

              Your  login  name  on  the NNTP server.  If unset and NNTP server requires authentication, NeoMutt
              will prompt you for your account name when you connect to news server.

       nntp_pass
              Type: string
              Default: ""

              Your password for NNTP account.

       nntp_poll
              Type: number
              Default: 60

              The time in seconds until any operations on newsgroup except post new article will  cause  recheck
              for  new  news.  If set to 0, NeoMutt will recheck newsgroup on each operation in index (stepping,
              read article, etc.).

       nm_open_timeout
              Type: number
              Default: 5

              This variable specifies the timeout for database open in seconds.

       nm_default_uri
              Type: string
              Default: ""

              This variable specifies the default Notmuch database in format notmuch://<absolute path>.

       nm_exclude_tags
              Type: string
              Default: ""

              The messages tagged with these tags are excluded and not loaded from notmuch DB to NeoMutt  unless
              specified explicitly.

       nm_unread_tag
              Type: string
              Default: "unread"

              This  variable  specifies  notmuch  tag which is used for unread messages. The variable is used to
              count unread messages in DB only. All other NeoMutt commands use standard (e.g. maildir) flags.

       nm_db_limit
              Type: number
              Default: 0

              This variable specifies the default limit used in notmuch queries.

       nm_query_type
              Type: string
              Default: "messages"

              This variable specifies the default query type (threads or messages) used in notmuch queries.

       nm_record
              Type: boolean
              Default: no

              This variable specifies if the NeoMutt record should indexed by notmuch.

       nm_record_tags
              Type: string
              Default: ""

              This variable specifies the default tags applied to messages stored to the NeoMutt  record.   When
              set to 0 this variable disable the window feature.

       nm_query_window_duration
              Type: number
              Default: 0

              This  variable  sets  the  time  base  of a windowed notmuch query.  Accepted values are 'minute',
              'hour', 'day', 'week', 'month', 'year'

       nm_query_window_timebase
              Type: string
              Default: "week"

              This variable sets the time duration of  a  windowed  notmuch  query.   Accepted  values  all  non
              negative integers. A value of 0 disables the feature.

       nm_query_window_current_search
              Type: string
              Default: ""

              This  variable  sets  the  time  duration  of  a  windowed notmuch query.  Accepted values all non
              negative integers. A value of 0 disables the feature.

       nm_query_window_current_position
              Type: number
              Default: 0

              This variable contains the currently setup notmuch search for window based vfolder.

       pager
              Type: path
              Default: "builtin"

              This variable specifies which pager you would like to use to view messages.  The  value  “builtin”
              means  to  use  the  built-in  pager,  otherwise  this variable should specify the pathname of the
              external pager you would like to use.

              Using an external pager may have some disadvantages: Additional keystrokes are  necessary  because
              you  can't  call  NeoMutt functions directly from the pager, and screen resizes cause lines longer
              than the screen width to be badly formatted in the help menu.

       hidden_tags
              Type: string
              Default: "unread,draft,flagged,passed,replied,attachment,signed,encrypted"

              This variable specifies private notmuch/imap tags which should not be printed on screen.

       pager_context
              Type: number
              Default: 0

              This variable controls the number of lines of context that are given when displaying the  next  or
              previous page in the internal pager.  By default, NeoMutt will display the line after the last one
              on the screen at the top of the next page (0 lines of context).

              This variable also specifies the amount of context given for search  results.  If  positive,  this
              many lines will be given before a match, if 0, the match will be top-aligned.

       pager_format
              Type: string
              Default: "-%Z- %C/%m: %-20.20n   %s%*  -- (%P)"

              This  variable  controls the format of the one-line message “status” displayed before each message
              in either the internal or an external pager.  The valid sequences are listed in the  $index_format
              section.

       pager_index_lines
              Type: number
              Default: 0

              Determines  the  number  of  lines  of a mini-index which is shown when in the pager.  The current
              message, unless near the top or bottom of the folder, will be roughly one third of  the  way  down
              this  mini-index,  giving  the  reader the context of a few messages before and after the message.
              This is useful, for example, to determine how many messages remain  to  be  read  in  the  current
              thread.   One  of  the lines is reserved for the status bar from the index, so a setting of 6 will
              only show 5 lines of the actual index.  A value of 0 results in no  index  being  shown.   If  the
              number of messages in the current folder is less than $pager_index_lines, then the index will only
              use as many lines as it needs.

       pager_stop
              Type: boolean
              Default: no

              When set, the internal-pager will not move to the next message when  you  are  at  the  end  of  a
              message and invoke the <next-page> function.

       pgp_auto_decode
              Type: boolean
              Default: no

              If  set,  NeoMutt will automatically attempt to decrypt traditional PGP messages whenever the user
              performs an operation which ordinarily would result in the contents of the message being  operated
              on.   For  example,  if  the  user  displays a pgp-traditional message which has not been manually
              checked with the <check-traditional-pgp> function, NeoMutt will automatically  check  the  message
              for traditional pgp.

       pgp_autoinline
              Type: boolean
              Default: no

              This  option  controls  whether  NeoMutt generates old-style inline (traditional) PGP encrypted or
              signed messages under certain circumstances.  This can be overridden by use of the pgp menu,  when
              inline is not required.  The GPGME backend does not support this option.

              Note  that  NeoMutt  might  automatically  use  PGP/MIME for messages which consist of more than a
              single MIME part.  NeoMutt can be configured to ask before sending PGP/MIME messages  when  inline
              (traditional) would not work.

              Also see the $pgp_mime_auto variable.

              Also note that using the old-style PGP message format is strongly deprecated.  (PGP only)

       pgp_check_exit
              Type: boolean
              Default: yes

              If  set,  NeoMutt  will  check  the exit code of the PGP subprocess when signing or encrypting.  A
              non-zero exit code means that the subprocess failed.  (PGP only)

       pgp_clearsign_command
              Type: string
              Default: ""

              This format is used to create an old-style “clearsigned” PGP message.  Note that the use  of  this
              format is strongly deprecated.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible printf(3)-like
              sequences.  (PGP only)

       pgp_decode_command
              Type: string
              Default: ""

              This format strings specifies a command which is used to decode application/pgp attachments.

              The PGP command formats have their own set of printf(3)-like sequences:
              %p     Expands to PGPPASSFD=0 when a pass phrase is needed, to an empty  string  otherwise.  Note:
                     This may be used with a %? construct.
              %f     Expands to the name of a file containing a message.
              %s     Expands to the name of a file containing the signature part
                                of a multipart/signed attachment when verifying it.
              %a     The value of $pgp_sign_as.
              %r     One or more key IDs (or fingerprints if available).

              For  examples on how to configure these formats for the various versions of PGP which are floating
              around, see the pgp and gpg sample configuration files in the samples/ subdirectory which has been
              installed on your system alongside the documentation.  (PGP only)

       pgp_decrypt_command
              Type: string
              Default: ""

              This command is used to decrypt a PGP encrypted message.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible printf(3)-like
              sequences.  (PGP only)

       pgp_decryption_okay
              Type: regular expression
              Default: ""

              If you assign text to this variable, then an encrypted PGP message is only considered successfully
              decrypted  if  the  output  from  $pgp_decrypt_command contains the text.  This is used to protect
              against a spoofed encrypted message, with multipart/encrypted headers but containing a block  that
              is not actually encrypted.  (e.g. simply signed and ascii armored text).  (PGP only)

       pgp_encrypt_only_command
              Type: string
              Default: ""

              This command is used to encrypt a body part without signing it.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible printf(3)-like
              sequences.  (PGP only)

       pgp_encrypt_sign_command
              Type: string
              Default: ""

              This command is used to both sign and encrypt a body part.

              This is  a  format  string,  see  the  $pgp_decode_command  command  for  possible  printf(3)-like
              sequences.  (PGP only)

       pgp_entry_format
              Type: string
              Default: "%4n %t%f %4l/0x%k %-4a %2c %u"

              This  variable  allows  you  to  customize the PGP key selection menu to your personal taste. This
              string is similar to $index_format, but has its own set of printf(3)-like sequences:
              %a     Algorithm
              %c     Capabilities
              %f     Flags
              %k     Key id
              %l     Key length
              %n     Number
              %p     Protocol
              %t     Trust/validity of the key-uid association
              %u     User id
              %[<s>] Date of the key where <s> is an strftime(3) expression

              (PGP only)

       pgp_export_command
              Type: string
              Default: ""

              This command is used to export a public key from the user's key ring.

              This is  a  format  string,  see  the  $pgp_decode_command  command  for  possible  printf(3)-like
              sequences.  (PGP only)

       pgp_getkeys_command
              Type: string
              Default: ""

              This  command  is  invoked whenever NeoMutt needs to fetch the public key associated with an email
              address.  Of the sequences  supported  by  $pgp_decode_command,  %r  is  the  only  printf(3)-like
              sequence  used with this format.  Note that in this case, %r expands to the email address, not the
              public key ID (the key ID is unknown, which is why NeoMutt is invoking this command).  (PGP only)

       pgp_good_sign
              Type: regular expression
              Default: ""

              If you assign a text to this variable, then a PGP signature is only  considered  verified  if  the
              output  from  $pgp_verify_command  contains  the text. Use this variable if the exit code from the
              command is 0 even for bad signatures.  (PGP only)

       pgp_ignore_subkeys
              Type: boolean
              Default: yes

              Setting this variable will cause NeoMutt to ignore OpenPGP subkeys.  Instead,  the  principal  key
              will  inherit the subkeys' capabilities.  Unset this if you want to play interesting key selection
              games.  (PGP only)

       pgp_import_command
              Type: string
              Default: ""

              This command is used to import a key from a message into the user's public key ring.

              This is  a  format  string,  see  the  $pgp_decode_command  command  for  possible  printf(3)-like
              sequences.  (PGP only)

       pgp_list_pubring_command
              Type: string
              Default: ""

              This  command is used to list the public key ring's contents.  The output format must be analogous
              to the one used by

              gpg --list-keys --with-colons --with-fingerprint

              This format is also generated by the pgpring utility which comes with NeoMutt.

              Note: gpg's fixed-list-mode option should not be used.  It produces a different date format  which
              may result in NeoMutt showing incorrect key generation dates.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible printf(3)-like
              sequences.  (PGP only)

       pgp_list_secring_command
              Type: string
              Default: ""

              This command is used to list the secret key ring's contents.  The output format must be  analogous
              to the one used by:

              gpg --list-keys --with-colons --with-fingerprint

              This format is also generated by the pgpring utility which comes with NeoMutt.

              Note:  gpg's fixed-list-mode option should not be used.  It produces a different date format which
              may result in NeoMutt showing incorrect key generation dates.

              This is  a  format  string,  see  the  $pgp_decode_command  command  for  possible  printf(3)-like
              sequences.  (PGP only)

       pgp_long_ids
              Type: boolean
              Default: yes

              If set, use 64 bit PGP key IDs, if unset use the normal 32 bit key IDs.  NOTE: Internally, NeoMutt
              has transitioned to using fingerprints (or long key IDs as a  fallback).   This  option  now  only
              controls the display of key IDs in the key selection menu and a few other places.  (PGP only)

       pgp_mime_auto
              Type: quadoption
              Default: ask-yes

              This   option   controls   whether   NeoMutt   will   prompt   you  for  automatically  sending  a
              (signed/encrypted) message using PGP/MIME when inline (traditional) fails (for any reason).

              Also note that using the old-style PGP message format is strongly deprecated.  (PGP only)

       pgp_replyinline
              Type: boolean
              Default: no

              Setting this variable will cause NeoMutt to always  attempt  to  create  an  inline  (traditional)
              message  when  replying to a message which is PGP encrypted/signed inline.  This can be overridden
              by use of the pgp menu, when inline is not required.  This option does not automatically detect if
              the  (replied-to)  message  is  inline;  instead  it  relies  on  NeoMutt internals for previously
              checked/flagged messages.

              Note that NeoMutt might automatically use PGP/MIME for messages  which  consist  of  more  than  a
              single  MIME  part.  NeoMutt can be configured to ask before sending PGP/MIME messages when inline
              (traditional) would not work.

              Also see the $pgp_mime_auto variable.

              Also note that using the old-style PGP message format is strongly deprecated.  (PGP only)

       pgp_retainable_sigs
              Type: boolean
              Default: no

              If  set,  signed  and  encrypted  messages   will   consist   of   nested   multipart/signed   and
              multipart/encrypted body parts.

              This  is  useful  for  applications like encrypted and signed mailing lists, where the outer layer
              (multipart/encrypted) can be easily removed, while the inner multipart/signed  part  is  retained.
              (PGP only)

       pgp_self_encrypt
              Type: boolean
              Default: no

              When  set,  PGP  encrypted  messages will also be encrypted using the key in $pgp_self_encrypt_as.
              (PGP only)

       pgp_self_encrypt_as
              Type: string
              Default: ""

              This is an additional key used to encrypt messages when $pgp_self_encrypt is set.  It is also used
              to  specify  the  key  for  $postpone_encrypt.   It  should  be in keyid or fingerprint form (e.g.
              0x00112233).  (PGP only)

       pgp_show_unusable
              Type: boolean
              Default: yes

              If set, NeoMutt will display non-usable keys on the PGP key selection menu.   This  includes  keys
              which have been revoked, have expired, or have been marked as “disabled” by the user.  (PGP only)

       pgp_sign_as
              Type: string
              Default: ""

              If  you  have more than one key pair, this option allows you to specify which of your private keys
              to use.  It is recommended that you use the keyid form to  specify  your  key  (e.g.  0x00112233).
              (PGP only)

       pgp_sign_command
              Type: string
              Default: ""

              This  command  is  used  to create the detached PGP signature for a multipart/signed PGP/MIME body
              part.

              This is  a  format  string,  see  the  $pgp_decode_command  command  for  possible  printf(3)-like
              sequences.  (PGP only)

       pgp_sort_keys
              Type: sort order
              Default: address

              Specifies how the entries in the pgp menu are sorted. The following are legal values:
              address
                     sort alphabetically by user id
              keyid  sort alphabetically by key id
              date   sort by key creation date
              trust  sort by the trust of the key

              If you prefer reverse order of the above values, prefix it with “reverse-”.  (PGP only)

       pgp_strict_enc
              Type: boolean
              Default: yes

              If  set,  NeoMutt  will automatically encode PGP/MIME signed messages as quoted-printable.  Please
              note that unsetting this variable may lead to problems with non-verifyable PGP signatures, so only
              change this if you know what you are doing.  (PGP only)

       pgp_timeout
              Type: number
              Default: 300

              The number of seconds after which a cached passphrase will expire if not used.  (PGP only)

       pgp_use_gpg_agent
              Type: boolean
              Default: no

              If  set,  NeoMutt  will use a possibly-running gpg-agent(1) process.  Note that as of version 2.1,
              GnuPG no longer exports GPG_AGENT_INFO, so NeoMutt no longer verifies if  the  agent  is  running.
              (PGP only)

       pgp_verify_command
              Type: string
              Default: ""

              This command is used to verify PGP signatures.

              This  is  a  format  string,  see  the  $pgp_decode_command  command  for  possible printf(3)-like
              sequences.  (PGP only)

       pgp_verify_key_command
              Type: string
              Default: ""

              This command is used to verify key information from the key selection menu.

              This is  a  format  string,  see  the  $pgp_decode_command  command  for  possible  printf(3)-like
              sequences.  (PGP only)

       pipe_decode
              Type: boolean
              Default: no

              Used  in  connection  with the <pipe-message> command.  When unset, NeoMutt will pipe the messages
              without any preprocessing. When set, NeoMutt will weed headers and  will  attempt  to  decode  the
              messages first.

       pipe_sep
              Type: string
              Default: "\n"

              The  separator  to  add between messages when piping a list of tagged messages to an external Unix
              command.

       pipe_split
              Type: boolean
              Default: no

              Used in connection with the <pipe-message> function following <tag-prefix>.  If this  variable  is
              unset,  when  piping a list of tagged messages NeoMutt will concatenate the messages and will pipe
              them all concatenated.  When set, NeoMutt will pipe the messages one by one.  In  both  cases  the
              messages  are  piped  in the current sorted order, and the $pipe_sep separator is added after each
              message.

       pop_auth_try_all
              Type: boolean
              Default: yes

              If set, NeoMutt will try all available authentication methods.  When unset, NeoMutt will only fall
              back  to  other  authentication  methods  if  the previous methods are unavailable. If a method is
              available but authentication fails, NeoMutt will not connect to the POP server.

       pop_authenticators
              Type: string
              Default: ""

              This is a colon-delimited list of authentication methods NeoMutt may attempt to use to log  in  to
              an  POP  server,  in the order NeoMutt should try them.  Authentication methods are either “user”,
              “apop” or any  SASL  mechanism,  e.g.  “digest-md5”,  “gssapi”  or  “cram-md5”.   This  option  is
              case-insensitive. If this option is unset (the default) NeoMutt will try all available methods, in
              order from most-secure to least-secure.

              Example:

              set pop_authenticators="digest-md5:apop:user"

       pop_checkinterval
              Type: number
              Default: 60

              This variable configures how often (in seconds) NeoMutt should look for new mail in the  currently
              selected mailbox if it is a POP mailbox.

       pop_delete
              Type: quadoption
              Default: ask-no

              If  set,  NeoMutt  will delete successfully downloaded messages from the POP server when using the
              <fetch-mail> function.  When unset, NeoMutt will download messages but also leave them on the  POP
              server.

       pop_host
              Type: string
              Default: ""

              The  name  of  your POP server for the <fetch-mail> function.  You can also specify an alternative
              port, username and password, i.e.:

              [pop[s]://][username[:password]@]popserver[:port]

              where “[...]” denotes an optional part.

       pop_last
              Type: boolean
              Default: no

              If this variable is set, NeoMutt will try to use the “LAST” POP command for retrieving only unread
              messages from the POP server when using the <fetch-mail> function.

       pop_pass
              Type: string
              Default: ""

              Specifies  the password for your POP account.  If unset, NeoMutt will prompt you for your password
              when you open a POP mailbox.

              Warning: you should only use this option when you are on a  fairly  secure  machine,  because  the
              superuser can read your neomuttrc even if you are the only one who can read the file.

       pop_reconnect
              Type: quadoption
              Default: ask-yes

              Controls whether or not NeoMutt will try to reconnect to the POP server if the connection is lost.

       pop_user
              Type: string
              Default: ""

              Your login name on the POP server.

              This variable defaults to your user name on the local machine.

       post_indent_string
              Type: string
              Default: ""

              Similar  to  the  $attribution  variable, NeoMutt will append this string after the inclusion of a
              message which is being replied to.

       post_moderated
              Type: quadoption
              Default: ask-yes

              If set to yes, NeoMutt will post article to newsgroup that have not permissions to  posting  (e.g.
              moderated).  Note: if news server does not support posting to that newsgroup or totally read-only,
              that posting will not have an effect.

       postpone
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are saved in the $postponed mailbox when you elect  not  to  send
              immediately.

              Also see the $recall variable.

       postponed
              Type: path
              Default: "~/postponed"

              NeoMutt  allows  you to indefinitely “postpone sending a message” which you are editing.  When you
              choose to postpone a message, NeoMutt saves it in the mailbox specified by this variable.

              Also see the $postpone variable.

       postpone_encrypt
              Type: boolean
              Default: no

              When set, postponed messages that are marked for encryption will be self-encrypted.  NeoMutt  will
              first  try to encrypt using the value specified in $pgp_self_encrypt_as or $smime_self_encrypt_as.
              If those are not set, it will try the deprecated $postpone_encrypt_as.  (Crypto only)

       postpone_encrypt_as
              Type: string
              Default: ""

              This is a deprecated fall-back variable for $postpone_encrypt.  Please use $pgp_self_encrypt_as or
              $smime_self_encrypt_as.  (Crypto only)

       preconnect
              Type: string
              Default: ""

              If  set,  a shell command to be executed if NeoMutt fails to establish a connection to the server.
              This is useful for setting up secure connections, e.g. with  ssh(1).  If  the  command  returns  a
              nonzero status, NeoMutt gives up opening the server. Example:

              set preconnect="ssh -f -q -L 1234:mailhost.net:143 mailhost.net \
              sleep 20 < /dev/null > /dev/null"

              Mailbox “foo” on “mailhost.net” can now be reached as “{localhost:1234}foo”.

              Note: For this example to work, you must be able to log in to the remote machine without having to
              enter a password.

       print
              Type: quadoption
              Default: ask-no

              Controls whether or not NeoMutt really prints messages.  This  is  set  to  “ask-no”  by  default,
              because some people accidentally hit “p” often.

       print_command
              Type: path
              Default: "lpr"

              This specifies the command pipe that should be used to print messages.

       print_decode
              Type: boolean
              Default: yes

              Used  in  connection  with  the  <print-message>  command.   If this option is set, the message is
              decoded before it is passed to the external command specified by $print_command.  If  this  option
              is  unset,  no processing will be applied to the message when printing it.  The latter setting may
              be useful if you are using some advanced printer filter which is able to  properly  format  e-mail
              messages for printing.

       print_split
              Type: boolean
              Default: no

              Used in connection with the <print-message> command.  If this option is set, the command specified
              by $print_command is executed once for each message which is to be printed.   If  this  option  is
              unset,  the  command  specified  by $print_command is executed only once, and all the messages are
              concatenated, with a form feed as the message separator.

              Those who use the enscript(1) program's mail-printing mode will  most  likely  want  to  set  this
              option.

       prompt_after
              Type: boolean
              Default: yes

              If  you  use  an  external  $pager,  setting  this variable will cause NeoMutt to prompt you for a
              command when the pager exits rather than returning to the index  menu.   If  unset,  NeoMutt  will
              return to the index menu when the external pager exits.

       query_command
              Type: path
              Default: ""

              This  specifies  the  command  NeoMutt  will use to make external address queries.  The string may
              contain a “%s”, which will be substituted with the query string the user types.  NeoMutt will  add
              quotes  around  the string substituted for “%s” automatically according to shell quoting rules, so
              you should avoid adding your own.  If no “%s” is found in the  string,  NeoMutt  will  append  the
              user's query to the end of the string.  See “query” for more information.

       query_format
              Type: string
              Default: "%4c %t %-25.25a %-25.25n %?e?(%e)?"

              This  variable  describes  the format of the “query” menu. The following printf(3)-style sequences
              are understood:
              %a     Destination address
              %c     Current entry number
              %e     Extra information *
              %n     Destination name
              %t     “*” if current entry is tagged, a space otherwise
              %>X    Right justify the rest of the string and pad with “X”
              %|X    Pad to the end of the line with “X”
              %*X    Soft-fill with character “X” as pad

              For an explanation of “soft-fill”, see the $index_format documentation.

              * = can be optionally printed if nonzero, see the $status_format documentation.

       quit
              Type: quadoption
              Default: yes

              This variable controls whether “quit” and “exit” actually quit from NeoMutt.  If  this  option  is
              set, they do quit, if it is unset, they have no effect, and if it is set to ask-yes or ask-no, you
              are prompted for confirmation when you try to quit.

       quote_regexp
              Type: regular expression
              Default: "^([ \t]*[|>:}#])+"

              A regular expression used in the internal pager to determine quoted sections of text in  the  body
              of  a  message.  Quoted  text  may  be  filtered out using the <toggle-quoted> command, or colored
              according to the “color quoted” family of directives.

              Higher levels of quoting may be colored differently (“color quoted1”, “color quoted2”, etc.).  The
              quoting  level  is determined by removing the last character from the matched text and recursively
              reapplying the regular expression until it fails to produce a match.

              Match detection may be overridden by the $smileys regular expression.

       read_inc
              Type: number
              Default: 10

              If set to a value greater than 0, NeoMutt will display which  message  it  is  currently  on  when
              reading  a  mailbox  or  when  performing  search actions such as search and limit. The message is
              printed after this many messages have been read or searched (e.g., if  set  to  25,  NeoMutt  will
              print  a  message  when  it  is  at  message 25, and then again when it gets to message 50).  This
              variable is meant to indicate progress when reading or searching large mailboxes  which  may  take
              some time.  When set to 0, only a single message will appear before the reading the mailbox.

              Also  see  the $write_inc, $net_inc and $time_inc variables and the “tuning” section of the manual
              for performance considerations.

       read_only
              Type: boolean
              Default: no

              If set, all folders are opened in read-only mode.

       realname
              Type: string
              Default: ""

              This variable specifies what “real” or “personal” name should be used when sending messages.

              By default, this is the GECOS field from /etc/passwd.  Note that this variable will  not  be  used
              when the user has set a real name in the $from variable.

       recall
              Type: quadoption
              Default: ask-yes

              Controls whether or not NeoMutt recalls postponed messages when composing a new message.

              Setting  this  variable  to  yes is not generally useful, and thus not recommended.  Note that the
              <recall-message> function can be used to manually recall postponed messages.

              Also see $postponed variable.

       record
              Type: path
              Default: "~/sent"

              This specifies the file into which your outgoing messages should be appended.  (This is  meant  as
              the  primary  method  for  saving a copy of your messages, but another way to do this is using the
              “my_hdr” command to create a “Bcc:” field with your email address in it.)

              The value of $record is overridden by the $force_name and $save_name variables, and the “fcc-hook”
              command.

       reflow_space_quotes
              Type: boolean
              Default: yes

              This  option  controls  how quotes from format=flowed messages are displayed in the pager and when
              replying (with $text_flowed unset).  When set, this option adds spaces after each level  of  quote
              marks, turning ">>>foo" into "> > > foo".

              Note:  If  $reflow_text  is  unset,  this option has no effect.  Also, this option does not affect
              replies when $text_flowed is set.

       reflow_text
              Type: boolean
              Default: yes

              When set, NeoMutt will reformat paragraphs in text/plain parts marked  format=flowed.   If  unset,
              NeoMutt  will  display paragraphs unaltered from how they appear in the message body.  See RFC3676
              for details on the format=flowed format.

              Also see $reflow_wrap, and $wrap.

       reflow_wrap
              Type: number
              Default: 78

              This variable controls the  maximum  paragraph  width  when  reformatting  text/plain  parts  when
              $reflow_text  is  set.   When  the  value is 0, paragraphs will be wrapped at the terminal's right
              margin.  A positive value sets the paragraph width relative to the left margin.  A negative  value
              set the paragraph width relative to the right margin.

              Also see $wrap.

       reply_regexp
              Type: regular expression
              Default: "^(re([\[0-9\]+])*|aw):[ \t]*"

              A  regular  expression  used  to recognize reply messages when threading and replying. The default
              value corresponds to the English "Re:" and the German "Aw:".

       reply_self
              Type: boolean
              Default: no

              If unset and you are replying to a message sent by you, NeoMutt will assume that you want to reply
              to the recipients of that message rather than to yourself.

              Also see the “alternates” command.

       reply_to
              Type: quadoption
              Default: ask-yes

              If set, when replying to a message, NeoMutt will use the address listed in the Reply-to: header as
              the recipient of the reply.  If unset, it will use the address in the From: header field  instead.
              This  option is useful for reading a mailing list that sets the Reply-To: header field to the list
              address and you want to send a private message to the author of a message.

       reply_with_xorig
              Type: boolean
              Default: no

              This variable provides a toggle. When active, the From: header will be extracted from the  current
              mail's `X-Original-To:' header. This setting does not have precedence over “reverse_realname”.

              Assuming `fast_reply' is disabled, this option will prompt the user with a prefilled From: header.

       resolve
              Type: boolean
              Default: yes

              When  set,  the  cursor  will  be  automatically advanced to the next (possibly undeleted) message
              whenever a command that modifies the current message is executed.

       resume_draft_files
              Type: boolean
              Default: no

              If set, draft files (specified by -H on the command line) are processed similarly to when resuming
              a  postponed  message.   Recipients  are  not prompted for; send-hooks are not evaluated; no alias
              expansion takes place; user-defined headers and signatures are not added to the message.

       resume_edited_draft_files
              Type: boolean
              Default: yes

              If  set,  draft  files  previously  edited  (via  -E  -H  on   the   command   line)   will   have
              $resume_draft_files automatically set when they are used as a draft file again.

              The  first time a draft file is saved, NeoMutt will add a header, X-Mutt-Resume-Draft to the saved
              file.  The next time the draft file  is  read  in,  if  NeoMutt  sees  the  header,  it  will  set
              $resume_draft_files.

              This option is designed to prevent multiple signatures, user-defined headers, and other processing
              effects from being made multiple times to the draft file.

       reverse_alias
              Type: boolean
              Default: no

              This variable controls whether or not NeoMutt will display the “personal” name from  your  aliases
              in  the  index  menu  if it finds an alias that matches the message's sender.  For example, if you
              have the following alias:

              alias juser abd30425@somewhere.net (Joe User)

              and then you receive mail which contains the following header:

              From: abd30425@somewhere.net

              It would be displayed in the index menu as “Joe User” instead of  “abd30425@somewhere.net.”   This
              is useful when the person's e-mail address is not human friendly.

       reverse_name
              Type: boolean
              Default: no

              It  may  sometimes arrive that you receive mail to a certain machine, move the messages to another
              machine, and reply to some the messages from there.  If this variable is set,  the  default  From:
              line  of  the  reply  messages  is built using the address where you received the messages you are
              replying to if that address matches your “alternates”.  If the variable is unset, or  the  address
              that  would  be  used doesn't match your “alternates”, the From: line will use your address on the
              current machine.

              Also see the “alternates” command.

       reverse_realname
              Type: boolean
              Default: yes

              This variable fine-tunes the behavior of the $reverse_name feature.  When it is set, NeoMutt  will
              use  the address from incoming messages as-is, possibly including eventual real names.  When it is
              unset, NeoMutt will override any such real names with the setting of the $realname variable.

       rfc2047_parameters
              Type: boolean
              Default: no

              When this variable is set, NeoMutt will decode RFC2047-encoded MIME parameters. You  want  to  set
              this variable when NeoMutt suggests you to save attachments to files named like:

              =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?=

              When this variable is set interactively, the change won't be active until you change folders.

              Note  that  this  use  of  RFC2047's  encoding  is  explicitly  prohibited  by  the  standard, but
              nevertheless encountered in the wild.

              Also note that setting this parameter will not have the effect that NeoMutt generates this kind of
              encoding.  Instead, NeoMutt will unconditionally use the encoding specified in RFC2231.

       save_address
              Type: boolean
              Default: no

              If  set,  NeoMutt  will take the sender's full address when choosing a default folder for saving a
              mail. If $save_name or $force_name is set too, the selection of the Fcc folder will be changed  as
              well.

       save_empty
              Type: boolean
              Default: yes

              When  unset,  mailboxes which contain no saved messages will be removed when closed (the exception
              is $spoolfile which is never removed).  If set, mailboxes are never removed.

              Note: This only applies to mbox  and  MMDF  folders,  NeoMutt  does  not  delete  MH  and  Maildir
              directories.

       save_history
              Type: number
              Default: 0

              This variable controls the size of the history (per category) saved in the $history_file file.

       save_name
              Type: boolean
              Default: no

              This  variable  controls  how copies of outgoing messages are saved.  When set, a check is made to
              see if a mailbox specified by the recipient address exists  (this  is  done  by  searching  for  a
              mailbox in the $folder directory with the username part of the recipient address).  If the mailbox
              exists, the outgoing message will be saved to that mailbox, otherwise the message is saved to  the
              $record mailbox.

              Also see the $force_name variable.

       score
              Type: boolean
              Default: yes

              When  this  variable  is  unset, scoring is turned off.  This can be useful to selectively disable
              scoring for certain folders when the $score_threshold_delete variable and related are used.

       score_threshold_delete
              Type: number
              Default: -1

              Messages which have been assigned a score equal to or lower than the value of  this  variable  are
              automatically  marked  for  deletion  by NeoMutt.  Since NeoMutt scores are always greater than or
              equal to zero, the default setting of this variable will never mark a message for deletion.

       score_threshold_flag
              Type: number
              Default: 9999

              Messages which have been assigned a score greater than or  equal  to  this  variable's  value  are
              automatically marked "flagged".

       score_threshold_read
              Type: number
              Default: -1

              Messages  which  have  been assigned a score equal to or lower than the value of this variable are
              automatically marked as read by NeoMutt.  Since NeoMutt scores are always greater than or equal to
              zero, the default setting of this variable will never mark a message read.

       search_context
              Type: number
              Default: 0

              For  the  pager,  this  variable  specifies  the  number  of lines shown before search results. By
              default, search results will be top-aligned.

       send_charset
              Type: string
              Default: "us-ascii:iso-8859-1:utf-8"

              A colon-delimited list of character sets  for  outgoing  messages.  NeoMutt  will  use  the  first
              character  set into which the text can be converted exactly.  If your $charset is not “iso-8859-1”
              and recipients may not understand “UTF-8”, it is advisable to include in the list  an  appropriate
              widely  used  standard  character  set  (such  as  “iso-8859-2”, “koi8-r” or “iso-2022-jp”) either
              instead of or after “iso-8859-1”.

              In case the text cannot be converted into one  of  these  exactly,  NeoMutt  uses  $charset  as  a
              fallback.

       sendmail
              Type: path
              Default: "/usr/sbin/sendmail -oem -oi"

              Specifies  the  program  and arguments used to deliver mail sent by NeoMutt.  NeoMutt expects that
              the specified program interprets additional arguments as recipient addresses.  NeoMutt appends all
              recipients  after  adding  a -- delimiter (if not already present).  Additional flags, such as for
              $use_8bitmime, $use_envelope_from, $dsn_notify, or $dsn_return will be added before the delimiter.

       sendmail_wait
              Type: number
              Default: 0

              Specifies the number of seconds to wait for the $sendmail process to finish before giving  up  and
              putting delivery in the background.

              NeoMutt interprets the value of this variable as follows:
              >0     number of seconds to wait for sendmail to finish before continuing
              0      wait forever for sendmail to finish
              <0     always put sendmail in the background without waiting

              Note  that  if  you specify a value other than 0, the output of the child process will be put in a
              temporary file.  If there is some error, you will be informed as to where to find the output.

       shell
              Type: path
              Default: ""

              Command to use when spawning a subshell.  By default, the user's login shell from  /etc/passwd  is
              used.

       save_unsubscribed
              Type: boolean
              Default: no

              When set, info about unsubscribed newsgroups will be saved into “newsrc” file and into cache.

       show_new_news
              Type: boolean
              Default: yes

              If  set, news server will be asked for new newsgroups on entering the browser.  Otherwise, it will
              be done only once for a news server.  Also controls whether or  not  number  of  new  articles  of
              subscribed newsgroups will be then checked.

       show_only_unread
              Type: boolean
              Default: no

              If set, only subscribed newsgroups that contain unread articles will be displayed in browser.

       sidebar_delim_chars
              Type: string
              Default: "/."

              This  contains  the  list  of  characters  which  you would like to treat as folder separators for
              displaying paths in the sidebar.

              Local mail is often arranged in directories: `dir1/dir2/mailbox'.

              set sidebar_delim_chars='/'

              IMAP mailboxes are often named: `folder1.folder2.mailbox'.

              set sidebar_delim_chars='.'

              See also: $sidebar_short_path, $sidebar_folder_indent, $sidebar_indent_string.

       sidebar_divider_char
              Type: string
              Default: ""

              This specifies the characters to be drawn between the sidebar (when visible) and the other NeoMutt
              panels. ASCII and Unicode line-drawing characters are supported.

       sidebar_folder_indent
              Type: boolean
              Default: no

              Set this to indent mailboxes in the sidebar.

              See also: $sidebar_short_path, $sidebar_indent_string, $sidebar_delim_chars.

       sidebar_format
              Type: string
              Default: "%B%*  %n"

              This   variable  allows  you  to  customize  the  sidebar  display.  This  string  is  similar  to
              $index_format, but has its own set of printf(3)-like sequences:
              %B     Name of the mailbox
              %S     * Size of mailbox (total number of messages)
              %N     * Number of unread messages in the mailbox
              %n     N if mailbox has new mail, blank otherwise
              %F     * Number of Flagged messages in the mailbox
              %!     “!” : one flagged message; “!!” : two flagged messages; “n!” : n flagged messages (for n  >
                     2).  Otherwise prints nothing.
              %d     * @ Number of deleted messages
              %L     * @ Number of messages after limiting
              %t     * @ Number of tagged messages
              %>X    right justify the rest of the string and pad with “X”
              %|X    pad to the end of the line with “X”
              %*X    soft-fill with character “X” as pad

              * = Can be optionally printed if nonzero @ = Only applicable to the current folder

              In  order  to  use  %S, %N, %F, and %!, $mail_check_stats must be set.  When thus set, a suggested
              value for this option is "%B%?F? [%F]?%* %?N?%N/?%S".

       sidebar_indent_string
              Type: string
              Default: "  "

              This specifies the string that is used to indent mailboxes in the sidebar.   It  defaults  to  two
              spaces.

              See also: $sidebar_short_path, $sidebar_folder_indent, $sidebar_delim_chars.

       sidebar_new_mail_only
              Type: boolean
              Default: no

              When set, the sidebar will only display mailboxes containing new, or flagged, mail.

              See also: sidebar_whitelist.

       sidebar_next_new_wrap
              Type: boolean
              Default: no

              When  set,  the <sidebar-next-new> command will not stop and the end of the list of mailboxes, but
              wrap around to the beginning. The  <sidebar-prev-new>  command  is  similarly  affected,  wrapping
              around to the end of the list.

       sidebar_on_right
              Type: boolean
              Default: no

              When set, the sidebar will appear on the right-hand side of the screen.

       sidebar_short_path
              Type: boolean
              Default: no

              By  default  the  sidebar  will show the mailbox's path, relative to the $folder variable. Setting
              sidebar_shortpath=yes will shorten the names relative to the previous name. Here's an example:
              shortpath=no
                     shortpath=yes shortpath=yes, folderindent=yes, indentstr=".."
              fruit  fruit fruit
              fruit.apple
                     apple ..apple
              fruit.banana
                     banana ..banana
              fruit.cherry
                     cherry ..cherry

              See     also:      $sidebar_delim_chars,      $sidebar_folder_indent,      $sidebar_indent_string,
              $sidebar_component_depth.

       sidebar_sort_method
              Type: sort order
              Default: order

              Specifies  how  to  sort  entries  in  the  file  browser.   By  default,  the  entries are sorted
              alphabetically.  Valid values:
              ‐ alpha (alphabetically)
              ‐ count (all message count)
              ‐ flagged (flagged message count)
              ‐ name (alphabetically)
              ‐ new (unread message count)
              ‐ path (alphabetically)
              ‐ unread (unread message count)
              ‐ unsorted

              You may optionally use the “reverse-” prefix to  specify  reverse  sorting  order  (example:  “set
              sort_browser=reverse-date”).

       sidebar_component_depth
              Type: number
              Default: 0

              By  default  the  sidebar  will  show  the  mailbox's path, relative to the $folder variable. This
              specifies the number of parent directories to hide from display in the sidebar. For example: If  a
              maildir    is   normally   displayed   in   the   sidebar   as   dir1/dir2/dir3/maildir,   setting
              sidebar_component_depth=2 will  display  it  as  dir3/maildir,  having  truncated  the  2  highest
              directories.

              See also: $sidebar_short_path

       sidebar_visible
              Type: boolean
              Default: no

              This specifies whether or not to show sidebar. The sidebar shows a list of all your mailboxes.

              See also: $sidebar_format, $sidebar_width

       sidebar_width
              Type: number
              Default: 30

              This  controls  the  width  of  the  sidebar.   It  is  measured  in screen columns.  For example:
              sidebar_width=20 could display 20 ASCII characters, or 10 Chinese characters.

       sig_dashes
              Type: boolean
              Default: yes

              If set, a line containing “-- ” (note the trailing space) will be inserted before your $signature.
              It  is  strongly  recommended that you not unset this variable unless your signature contains just
              your name.  The reason for this is because many software packages  use  “--  \n”  to  detect  your
              signature.   For  example, NeoMutt has the ability to highlight the signature in a different color
              in the built-in pager.

       sig_on_top
              Type: boolean
              Default: no

              If set, the signature will be included before any  quoted  or  forwarded  text.   It  is  strongly
              recommended  that  you do not set this variable unless you really know what you are doing, and are
              prepared to take some heat from netiquette guardians.

       signature
              Type: path
              Default: "~/.signature"

              Specifies the filename of your signature, which is appended to all  outgoing  messages.    If  the
              filename  ends  with a pipe (“|”), it is assumed that filename is a shell command and input should
              be read from its standard output.

       simple_search
              Type: string
              Default: "~f %s | ~s %s"

              Specifies how NeoMutt should expand a simple search into a real search pattern.  A  simple  search
              is  one  that  does  not  contain  any  of  the  “~”  pattern  operators.  See “patterns” for more
              information on search patterns.

              For example, if you simply type “joe” at a search or  limit  prompt,  NeoMutt  will  automatically
              expand it to the value specified by this variable by replacing “%s” with the supplied string.  For
              the default value, “joe” would be expanded to: “~f joe | ~s joe”.

       skip_quoted_offset
              Type: number
              Default: 0

              Lines of quoted text that are displayed before the unquoted text after “skip  to  quoted”  command
              (S)

       sleep_time
              Type: number
              Default: 1

              Specifies time, in seconds, to pause while displaying certain informational messages, while moving
              from folder to folder and after expunging messages from the current folder.   The  default  is  to
              pause one second, so a value of zero for this option suppresses the pause.

       smart_wrap
              Type: boolean
              Default: yes

              Controls  the  display  of  lines longer than the screen width in the internal pager. If set, long
              lines are wrapped at a word boundary.  If unset, lines are simply wrapped at the screen edge. Also
              see the $markers variable.

       smileys
              Type: regular expression
              Default: "(>From )|(:[-^]?[][)(><}{|/DP])"

              The  pager  uses this variable to catch some common false positives of $quote_regexp, most notably
              smileys and not consider a line quoted text if it also matches $smileys. This  mostly  happens  at
              the beginning of a line.

       smime_ask_cert_label
              Type: boolean
              Default: yes

              This  flag  controls  whether  you want to be asked to enter a label for a certificate about to be
              added to the database or not. It is set by default.  (S/MIME only)

       smime_ca_location
              Type: path
              Default: ""

              This variable contains the  name  of  either  a  directory,  or  a  file  which  contains  trusted
              certificates for use with OpenSSL.  (S/MIME only)

       smime_certificates
              Type: path
              Default: ""

              Since  for  S/MIME  there  is  no  pubring/secring  as with PGP, NeoMutt has to handle storage and
              retrieval of keys by itself. This is very basic right now, and keys and certificates are stored in
              two  different directories, both named as the hash-value retrieved from OpenSSL. There is an index
              file which contains mailbox-address keyid pairs, and which can be  manually  edited.  This  option
              points to the location of the certificates.  (S/MIME only)

       smime_decrypt_command
              Type: string
              Default: ""

              This  format  string  specifies  a  command  which  is  used  to  decrypt application/x-pkcs7-mime
              attachments.

              The OpenSSL command formats have their own set of printf(3)-like sequences similar to PGP's:
              %f     Expands to the name of a file containing a message.
              %s     Expands to the name of a file containing the signature part
                                of a multipart/signed attachment when verifying it.
              %k     The key-pair specified with $smime_default_key
              %i     Intermediate certificates
              %c     One or more certificate IDs.
              %a     The algorithm used for encryption.
              %d     The message digest algorithm specified with $smime_sign_digest_alg.
              %C     CA location:  Depending on whether $smime_ca_location
                                points to a directory or file, this expands to
                                “-CApath $smime_ca_location” or “-CAfile $smime_ca_location”.

              For examples on how to configure these formats, see the  smime.rc  in  the  samples/  subdirectory
              which has been installed on your system alongside the documentation.  (S/MIME only)

       smime_decrypt_use_default_key
              Type: boolean
              Default: yes

              If  set (default) this tells NeoMutt to use the default key for decryption. Otherwise, if managing
              multiple certificate-key-pairs, NeoMutt will try to use the mailbox-address to determine  the  key
              to use. It will ask you to supply a key, if it can't find one.  (S/MIME only)

       smime_default_key
              Type: string
              Default: ""

              This  is  the  default  key-pair to use for signing. This must be set to the keyid (the hash-value
              that OpenSSL generates) to work properly (S/MIME only)

       smime_encrypt_command
              Type: string
              Default: ""

              This command is used to create encrypted S/MIME messages.

              This is a format string,  see  the  $smime_decrypt_command  command  for  possible  printf(3)-like
              sequences.  (S/MIME only)

              Encrypt the message to $smime_default_key too.  (S/MIME only)

       smime_encrypt_with
              Type: string
              Default: "aes256"

              This sets the algorithm that should be used for encryption.  Valid choices are “aes128”, “aes192”,
              “aes256”, “des”, “des3”, “rc2-40”, “rc2-64”, “rc2-128”.  (S/MIME only)

       smime_get_cert_command
              Type: string
              Default: ""

              This command is used to extract X509 certificates from a PKCS7 structure.

              This is a format string,  see  the  $smime_decrypt_command  command  for  possible  printf(3)-like
              sequences.  (S/MIME only)

       smime_get_cert_email_command
              Type: string
              Default: ""

              This  command  is used to extract the mail address(es) used for storing X509 certificates, and for
              verification purposes (to check whether the certificate was issued for the sender's mailbox).

              This is a format string,  see  the  $smime_decrypt_command  command  for  possible  printf(3)-like
              sequences.  (S/MIME only)

       smime_get_signer_cert_command
              Type: string
              Default: ""

              This command is used to extract only the signers X509 certificate from a S/MIME signature, so that
              the certificate's owner may get compared to the email's “From:” field.

              This is a format string,  see  the  $smime_decrypt_command  command  for  possible  printf(3)-like
              sequences.  (S/MIME only)

       smime_import_cert_command
              Type: string
              Default: ""

              This command is used to import a certificate via smime_keys.

              This  is  a  format  string,  see  the  $smime_decrypt_command command for possible printf(3)-like
              sequences.  (S/MIME only)

       smime_is_default
              Type: boolean
              Default: no

              The default behavior of NeoMutt is to use PGP on all auto-sign/encryption operations. To  override
              and  to  use  OpenSSL instead this must be set.  However, this has no effect while replying, since
              NeoMutt will automatically select the same application that was used to sign/encrypt the  original
              message.   (Note  that  this  variable  can be overridden by unsetting $crypt_autosmime.)  (S/MIME
              only)

       smime_keys
              Type: path
              Default: ""

              Since for S/MIME there is no pubring/secring as with  PGP,  NeoMutt  has  to  handle  storage  and
              retrieval  of keys/certs by itself. This is very basic right now, and stores keys and certificates
              in two different directories, both named as the hash-value retrieved from  OpenSSL.  There  is  an
              index  file  which  contains  mailbox-address  keyid  pair, and which can be manually edited. This
              option points to the location of the private keys.  (S/MIME only)

       smime_pk7out_command
              Type: string
              Default: ""

              This command is used to extract PKCS7 structures of S/MIME signatures, in  order  to  extract  the
              public X509 certificate(s).

              This  is  a  format  string,  see  the  $smime_decrypt_command command for possible printf(3)-like
              sequences.  (S/MIME only)

       smime_self_encrypt
              Type: boolean
              Default: no

              When  set,  S/MIME  encrypted  messages  will  also  be  encrypted  using   the   certificate   in
              $smime_self_encrypt_as.  (S/MIME only)

       smime_self_encrypt_as
              Type: string
              Default: ""

              This is an additional certificate used to encrypt messages when $smime_self_encrypt is set.  It is
              also used to specify the certificate for $postpone_encrypt.  It  should  be  the  hash-value  that
              OpenSSL generates.  (S/MIME only)

       smime_sign_command
              Type: string
              Default: ""

              This  command  is used to created S/MIME signatures of type multipart/signed, which can be read by
              all mail clients.

              This is a format string,  see  the  $smime_decrypt_command  command  for  possible  printf(3)-like
              sequences.  (S/MIME only)

       smime_sign_digest_alg
              Type: string
              Default: "sha256"

              This  sets  the algorithm that should be used for the signature message digest.  Valid choices are
              “md5”, “sha1”, “sha224”, “sha256”, “sha384”, “sha512”.  (S/MIME only)

       smime_timeout
              Type: number
              Default: 300

              The number of seconds after which a cached passphrase will expire if not used.  (S/MIME only)

       smime_verify_command
              Type: string
              Default: ""

              This command is used to verify S/MIME signatures of type multipart/signed.

              This is a format string,  see  the  $smime_decrypt_command  command  for  possible  printf(3)-like
              sequences.  (S/MIME only)

       smime_verify_opaque_command
              Type: string
              Default: ""

              This command is used to verify S/MIME signatures of type application/x-pkcs7-mime.

              This  is  a  format  string,  see  the  $smime_decrypt_command command for possible printf(3)-like
              sequences.  (S/MIME only)

              Note: On Debian systems, this  defaults  to  the  first  existing  file  in  the  following  list:
              ~/.smime/ca-certificates.crt ~/.smime/ca-bundle.crt /etc/ssl/certs/ca-certificates.crt.

       smtp_authenticators
              Type: string
              Default: ""

              This  is  a colon-delimited list of authentication methods NeoMutt may attempt to use to log in to
              an SMTP server, in the order NeoMutt  should  try  them.   Authentication  methods  are  any  SASL
              mechanism,  e.g.  “plain”, “digest-md5”, “gssapi” or “cram-md5”.  This option is case-insensitive.
              If it is “unset” (the default) NeoMutt will try all available methods, in order  from  most-secure
              to least-secure. Support for the “plain” mechanism is bundled; other mechanisms are provided by an
              external SASL library (look for +USE_SASL in the output of neomutt -v).

              Example:

              set smtp_authenticators="digest-md5:cram-md5"

       smtp_pass
              Type: string
              Default: ""

              Specifies the password for your SMTP account.  If unset, NeoMutt will prompt you for your password
              when you first send mail via SMTP.  See $smtp_url to configure NeoMutt to send mail via SMTP.

              Warning:  you  should  only  use  this option when you are on a fairly secure machine, because the
              superuser can read your neomuttrc even if you are the only one who can read the file.

       smtp_url
              Type: string
              Default: ""

              Defines the SMTP smarthost where sent messages should relayed for delivery. This should  take  the
              form of an SMTP URL, e.g.:

              smtp[s]://[user[:pass]@]host[:port]

              where  “[...]”  denotes  an  optional  part.   Setting  this  variable  overrides the value of the
              $sendmail variable.

       sort
              Type: sort order
              Default: date

              Specifies how to sort messages in the “index” menu.  Valid values are:
              ‐ date or date-sent
              ‐ date-received
              ‐ from
              ‐ mailbox-order (unsorted)
              ‐ score
              ‐ size
              ‐ spam
              ‐ subject
              ‐ threads
              ‐ to

              You may optionally use the “reverse-” prefix to specify reverse sorting order.

              Example:

              set sort=reverse-date-sent

       sort_alias
              Type: sort order
              Default: alias

              Specifies how the entries in the “alias” menu are sorted.  The following are legal values:
              ‐ address (sort alphabetically by email address)
              ‐ alias (sort alphabetically by alias name)
              ‐ unsorted (leave in order specified in .neomuttrc)

       sort_aux
              Type: sort order
              Default: date

              When sorting by threads, this variable controls how  threads  are  sorted  in  relation  to  other
              threads,  and  how the branches of the thread trees are sorted.  This can be set to any value that
              $sort can, except “threads” (in that case, NeoMutt will  just  use  “date-sent”).   You  can  also
              specify  the  “last-”  prefix  in  addition  to the “reverse-” prefix, but “last-” must come after
              “reverse-”.  The “last-” prefix causes messages to be sorted against its siblings by which has the
              last descendant, using the rest of $sort_aux as an ordering.  For instance,

              set sort_aux=last-date-received

              would  mean  that  if  a  new  message  is  received in a thread, that thread becomes the last one
              displayed (or the first, if you have “set sort=reverse-threads”.)

              Note: For reversed $sort order $sort_aux is reversed again (which is not the right  thing  to  do,
              but kept to not break any existing configuration setting).

       sort_browser
              Type: sort order
              Default: alpha

              Specifies  how  to  sort  entries  in  the  file  browser.   By  default,  the  entries are sorted
              alphabetically.  Valid values:
              ‐ alpha (alphabetically)
              ‐ count (all message count)
              ‐ date
              ‐ desc (description)
              ‐ new (new message count)
              ‐ size
              ‐ unsorted

              You may optionally use the “reverse-” prefix to  specify  reverse  sorting  order  (example:  “set
              sort_browser=reverse-date”).

       sort_re
              Type: boolean
              Default: yes

              This  variable  is  only  useful  when  sorting  by  mailboxes in sidebar. By default, entries are
              unsorted.  Valid values:
              ‐ count (all message count)
              ‐ desc  (virtual mailbox description)
              ‐ new (new message count)
              ‐ path
              ‐ unsorted

       spam_separator
              Type: string
              Default: ","

              This variable controls what happens when  multiple  spam  headers  are  matched:  if  unset,  each
              successive  header  will  overwrite  any  previous  matches value for the spam label. If set, each
              successive match will append to the previous, using this variable's value as a separator.

       spoolfile
              Type: path
              Default: ""

              If your spool mailbox is in a non-default place where NeoMutt cannot find it, you can specify  its
              location  with  this  variable.   NeoMutt  will  initially  set  this variable to the value of the
              environment variable $MAIL or $MAILDIR if either is defined.

       ssl_ca_certificates_file
              Type: path
              Default: ""

              This variable specifies a file containing trusted CA certificates.  Any server certificate that is
              signed with one of these CA certificates is also automatically accepted. (GnuTLS only)

              Example:

              set ssl_ca_certificates_file=/etc/ssl/certs/ca-certificates.crt

              Note: On Debian systems, this option is set by default to “threads” in /etc/Muttrc.

       ssl_client_cert
              Type: path
              Default: ""

              The file containing a client certificate and its associated private key.

       ssl_force_tls
              Type: boolean
              Default: no

              If this variable is set, NeoMutt will require that all connections to remote servers be encrypted.
              Furthermore it will attempt to negotiate TLS even if the server does not advertise the capability,
              since   it   would  otherwise  have  to  abort  the  connection  anyway.  This  option  supersedes
              $ssl_starttls.

       ssl_min_dh_prime_bits
              Type: number
              Default: 0

              This variable specifies the minimum acceptable prime size (in bits) for use in any  Diffie-Hellman
              key exchange. A value of 0 will use the default from the GNUTLS library. (GnuTLS only)

       ssl_starttls
              Type: quadoption
              Default: yes

              If  set (the default), NeoMutt will attempt to use STARTTLS on servers advertising the capability.
              When unset, NeoMutt will not attempt to use STARTTLS regardless of the server's capabilities.

       ssl_use_sslv3
              Type: boolean
              Default: no

              This variable specifies whether to attempt to use SSLv3 in the SSL  authentication  process.  Note
              that SSLv2 and SSLv3 are now considered fundamentally insecure and are no longer recommended.

       ssl_use_tlsv1
              Type: boolean
              Default: yes

              This variable specifies whether to attempt to use TLSv1.0 in the SSL authentication process.

       ssl_use_tlsv1_1
              Type: boolean
              Default: yes

              This variable specifies whether to attempt to use TLSv1.1 in the SSL authentication process.

       ssl_use_tlsv1_2
              Type: boolean
              Default: yes

              This variable specifies whether to attempt to use TLSv1.2 in the SSL authentication process.

       ssl_verify_dates
              Type: boolean
              Default: yes

              If  set  (the  default), NeoMutt will not automatically accept a server certificate that is either
              not yet valid or already expired. You should only unset this for particular known hosts, using the
              <account-hook> function.

       ssl_verify_host
              Type: boolean
              Default: yes

              If  set  (the default), NeoMutt will not automatically accept a server certificate whose host name
              does not match the host used in your folder URL. You should only unset this for  particular  known
              hosts, using the <account-hook> function.

       ssl_ciphers
              Type: string
              Default: ""

              Contains a colon-separated list of ciphers to use when using SSL.  For OpenSSL, see ciphers(1) for
              the syntax of the string.

              For GnuTLS, this option will be used in place of "NORMAL" at the start  of  the  priority  string.
              See gnutls_priority_init(3) for the syntax and more details. (Note: GnuTLS version 2.1.7 or higher
              is required.)

       status_chars
              Type: string
              Default: "-*%A"

              Controls the characters used by the “%r” indicator in $status_format.
              Character
                     Default Description
              1      - Mailbox is unchanged
              2      * Mailbox has been changed and needs to be resynchronized
              3      % Mailbox is read-only, or will not be written when exiting.  (You can  toggle  whether  to
                     write changes to a mailbox with the <toggle-write> operation, bound by default to “%”)
              4      A  Folder  opened  in  attach-message mode.  (Certain operations like composing a new mail,
                     replying, forwarding, etc. are not permitted in this mode)

       status_format
              Type: string
              Default: "-%r-NeoMutt: %f [Msgs:%?M?%M/?%m%?n? New:%n?%?o? Old:%o?%?d? Del:%d?%?F? Flag:%F?%?t? Tag:%t?%?p? Post:%p?%?b? Inc:%b?%?l? %l?]---(%s/%S)-%>-(%P)---"

              Controls the format of the status line displayed in the “index” menu.  This string is  similar  to
              $index_format, but has its own set of printf(3)-like sequences:
              %b     Number of mailboxes with new mail *
              %d     Number of deleted messages *
              %f     The full pathname of the current mailbox
              %F     Number of flagged messages *
              %h     Local hostname
              %l     Size (in bytes) of the current mailbox *
              %L     Size (in bytes) of the messages shown (i.e., which match the current limit) *
              %m     The number of messages in the mailbox *
              %M     The number of messages shown (i.e., which match the current limit) *
              %n     Number of new messages in the mailbox *
              %o     Number of old unread messages *
              %p     Number of postponed messages *
              %P     Percentage of the way through the index
              %r     Modified/read-only/won't-write/attach-message indicator, According to $status_chars
              %R     Number of read messages *
              %s     Current sorting mode ($sort)
              %S     Current aux sorting method ($sort_aux)
              %t     Number of tagged messages *
              %u     Number of unread messages *
              %v     NeoMutt version string
              %V     Currently active limit pattern, if any *
              %>X    Right justify the rest of the string and pad with “X”
              %|X    Pad to the end of the line with “X”
              %*X    Soft-fill with character “X” as pad

              For an explanation of “soft-fill”, see the $index_format documentation.

              * = can be optionally printed if nonzero

              Some  of  the  above sequences can be used to optionally print a string if their value is nonzero.
              For example, you may only want to see the number of flagged messages if such messages exist, since
              zero  is  not  particularly  meaningful.  To optionally print a string based upon one of the above
              sequences, the following construct is used:

              %?<sequence_char>?<optional_string>?

              where sequence_char is a character from the table above, and optional_string  is  the  string  you
              would  like  printed  if sequence_char is nonzero.  optional_string may contain other sequences as
              well as normal text, but you may not nest optional strings.

              Here is an example illustrating how to optionally print the number of new messages in a mailbox:

              %?n?%n new messages.?

              You can also switch between two strings using the following construct:

              %?<sequence_char>?<if_string>&<else_string>?

              If the value of sequence_char is non-zero, if_string will be expanded, otherwise else_string  will
              be expanded.

              You  can force the result of any printf(3)-like sequence to be lowercase by prefixing the sequence
              character with an underscore (“_”) sign.  For example, if you want to display the  local  hostname
              in lowercase, you would use: “%_h”.

              If  you  prefix the sequence character with a colon (“:”) character, NeoMutt will replace any dots
              in the expansion by underscores. This might be helpful with IMAP folders that don't like  dots  in
              folder names.

       status_on_top
              Type: boolean
              Default: no

              Setting  this  variable  causes  the  “status bar” to be displayed on the first line of the screen
              rather than near the bottom. If $help is set, too it'll be placed at the bottom.

       strict_threads
              Type: boolean
              Default: no

              If set, threading will only make use of the “In-Reply-To” and “References:” fields when you  $sort
              by  message  threads.   By default, messages with the same subject are grouped together in “pseudo
              threads.”. This may not always be desirable, such as in a personal mailbox where  you  might  have
              several  unrelated  messages with the subjects like “hi” which will get grouped together. See also
              $sort_re for a less drastic way of controlling this behavior.

       suspend
              Type: boolean
              Default: yes

              When unset, NeoMutt won't stop when the user presses the terminal's susp key, usually  “^Z”.  This
              is useful if you run NeoMutt inside an xterm using a command like “xterm -e neomutt”.

       text_flowed
              Type: boolean
              Default: no

              When  set,  NeoMutt  will  generate  “format=flowed”  bodies  with  a content type of “text/plain;
              format=flowed”.  This format is easier to handle for some mailing  software,  and  generally  just
              looks  like ordinary text.  To actually make use of this format's features, you'll need support in
              your editor.

              Note that $indent_string is ignored when this option is set.

       thorough_search
              Type: boolean
              Default: yes

              Affects the ~b and ~h search operations described in section “patterns”.  If set, the headers  and
              body/attachments  of  messages to be searched are decoded before searching. If unset, messages are
              searched as they appear in the folder.

              Users searching attachments or for non-ASCII characters should set  this  value  because  decoding
              also includes MIME parsing/decoding and possible character set conversions. Otherwise NeoMutt will
              attempt to match against the raw message received (for example quoted-printable  encoded  or  with
              encoded headers) which may lead to incorrect search results.

       thread_received
              Type: boolean
              Default: no

              When set, NeoMutt uses the date received rather than the date sent to thread messages by subject.

       tilde
              Type: boolean
              Default: no

              When set, the internal-pager will pad blank lines to the bottom of the screen with a tilde (“~”).

       time_inc
              Type: number
              Default: 0

              Along  with  $read_inc,  $write_inc, and $net_inc, this variable controls the frequency with which
              progress updates are displayed. It suppresses updates less than $time_inc milliseconds apart. This
              can improve throughput on systems with slow terminals, or when running NeoMutt on a remote system.

              Also see the “tuning” section of the manual for performance considerations.

       timeout
              Type: number
              Default: 600

              When NeoMutt is waiting for user input either idling in menus or in an interactive prompt, NeoMutt
              would block until input  is  present.  Depending  on  the  context,  this  would  prevent  certain
              operations from working, like checking for new mail or keeping an IMAP connection alive.

              This  variable  controls  how  many  seconds NeoMutt will at most wait until it aborts waiting for
              input, performs these operations and continues to wait for input.

              A value of zero or less will cause NeoMutt to never time out.

       tmpdir
              Type: path
              Default: ""

              This variable allows you to specify where NeoMutt  will  place  its  temporary  files  needed  for
              displaying  and composing messages.  If this variable is not set, the environment variable $TMPDIR
              is used.  If $TMPDIR is not set then “/tmp” is used.

       to_chars
              Type: string
              Default: " +TCFL"

              Controls the character used to indicate mail addressed to you.
              Character
                     Default Description
              1      <space> The mail is not addressed to your address.
              2      + You are the only recipient of the message.
              3      T Your address appears in the “To:” header field, but you are not the only recipient of the
                     message.
              4      C Your address is specified in the “Cc:” header field, but you are not the only recipient.
              5      F Indicates the mail that was sent by you.
              6      L Indicates the mail was sent to a mailing-list you subscribe to.

       flag_chars
              Type: string
              Default: "*!DdrONon- "

              Controls the characters used in several flags.
              Character
                     Default Description
              1      * The mail is tagged.
              2      !  The mail is flagged as important.
              3      D The mail is marked for deletion.
              4      d The mail has attachments marked for deletion.
              5      r The mail has been replied to.
              6      O The mail is Old (Unread but seen).
              7      N The mail is New (Unread but not seen).
              8      o The mail thread is Old (Unread but seen).
              9      n The mail thread is New (Unread but not seen).
              10     - The mail is read - %S expando.
              11     <space> The mail is read - %Z expando.

       trash
              Type: path
              Default: ""

              If  set,  this variable specifies the path of the trash folder where the mails marked for deletion
              will be moved, instead of being irremediably purged.

              NOTE: When you delete a message in the trash folder, it is really deleted, so that you have a  way
              to clean the trash.

       ts_icon_format
              Type: string
              Default: "M%?n?AIL&ail?"

              Controls  the format of the icon title, as long as “$ts_enabled” is set.  This string is identical
              in formatting to the one used by “$status_format”.

       ts_enabled
              Type: boolean
              Default: no

              Controls whether NeoMutt tries to set the terminal status  line  and  icon  name.   Most  terminal
              emulators emulate the status line in the window title.

       ts_status_format
              Type: string
              Default: "NeoMutt with %?m?%m messages&no messages?%?n? [%n NEW]?"

              Controls the format of the terminal status line (or window title), provided that “$ts_enabled” has
              been set. This string is identical in formatting to the one used by “$status_format”.

       tunnel
              Type: string
              Default: ""

              Setting this variable will cause NeoMutt to open a pipe to a command instead of a raw socket.  You
              may  be  able  to  use  this to set up preauthenticated connections to your IMAP/POP3/SMTP server.
              Example:

              set tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"

              Note: For this example to work you must be able to log in to the remote machine without having  to
              enter a password.

              When  set,  NeoMutt  uses the tunnel for all remote connections.  Please see “account-hook” in the
              manual for how to use different tunnel commands per connection.

       uncollapse_jump
              Type: boolean
              Default: no

              When set, NeoMutt will jump to the next unread  message,  if  any,  when  the  current  thread  is
              uncollapsed.

       uncollapse_new
              Type: boolean
              Default: yes

              When  set, NeoMutt will automatically uncollapse any collapsed thread that receives a new message.
              When unset, collapsed threads will remain collapsed. the presence of the new  message  will  still
              affect index sorting, though.

       use_8bitmime
              Type: boolean
              Default: no

              Warning:  do  not  set this variable unless you are using a version of sendmail which supports the
              -B8BITMIME flag (such as sendmail 8.8.x) or you may not be able to send mail.

              When set, NeoMutt will invoke $sendmail with the -B8BITMIME flag when sending  8-bit  messages  to
              enable ESMTP negotiation.

       use_domain
              Type: boolean
              Default: yes

              When  set,  NeoMutt  will  qualify all local addresses (ones without the “@host” portion) with the
              value of $hostname.  If unset, no addresses will be qualified.

       use_envelope_from
              Type: boolean
              Default: no

              When set, NeoMutt will set the envelope sender of the message.  If $envelope_from_address is  set,
              it  will  be  used as the sender address. If unset, NeoMutt will attempt to derive the sender from
              the “From:” header.

              Note that this information is passed to  sendmail  command  using  the  -f  command  line  switch.
              Therefore  setting  this  option is not useful if the $sendmail variable already contains -f or if
              the executable pointed to by $sendmail doesn't support the -f switch.

       use_from
              Type: boolean
              Default: yes

              When set, NeoMutt will generate the “From:” header field when  sending  messages.   If  unset,  no
              “From:”  header  field  will  be  generated unless the user explicitly sets one using the “my_hdr”
              command.

       use_ipv6
              Type: boolean
              Default: yes

              When set, NeoMutt will look for IPv6 addresses of hosts it tries to contact.  If  this  option  is
              unset, NeoMutt will restrict itself to IPv4 addresses.  Normally, the default should work.

       user_agent
              Type: boolean
              Default: yes

              When  set,  NeoMutt will add a “User-Agent:” header to outgoing messages, indicating which version
              of NeoMutt was used for composing them.

       visual
              Type: path
              Default: ""

              Specifies the visual editor to invoke when the “~v” command is given in the built-in editor.

       vfolder_format
              Type: string
              Default: "%2C %?n?%4n/&     ?%4m %f"

              This variable allows you to customize the  file  browser  display  for  virtual  folders  to  your
              personal taste.  This string uses many of the same expandos as $folder_format.

       virtual_spoolfile
              Type: boolean
              Default: no

              When  set,  NeoMutt  will use the first defined virtual mailbox (see virtual-mailboxes) as a spool
              file.

       wait_key
              Type: boolean
              Default: yes

              Controls whether NeoMutt will ask you to press a key after an external command has been invoked by
              these  functions: <shell-escape>, <pipe-message>, <pipe-entry>, <print-message>, and <print-entry>
              commands.

              It is also used when viewing attachments with “auto_view”, provided that the corresponding mailcap
              entry has a needsterminal flag, and the external program is interactive.

              When  set,  NeoMutt will always ask for a key. When unset, NeoMutt will wait for a key only if the
              external command returned a non-zero status.

       weed
              Type: boolean
              Default: yes

              When set, NeoMutt will  weed  headers  when  displaying,  forwarding,  printing,  or  replying  to
              messages.

       wrap
              Type: number
              Default: 0

              When  set to a positive value, NeoMutt will wrap text at $wrap characters.  When set to a negative
              value, NeoMutt will wrap text so that there are $wrap characters of empty space on the right  side
              of the terminal. Setting it to zero makes NeoMutt wrap at the terminal width.

              Also see $reflow_wrap.

       wrap_headers
              Type: number
              Default: 78

              This  option specifies the number of characters to use for wrapping an outgoing message's headers.
              Allowed values are between 78 and 998 inclusive.

              Note: This option usually shouldn't be changed. RFC5233  recommends  a  line  length  of  78  (the
              default), so please only change this setting when you know what you're doing.

       wrap_search
              Type: boolean
              Default: yes

              Controls whether searches wrap around the end.

              When  set,  searches  will  wrap around the first (or last) item. When unset, incremental searches
              will not wrap.

       wrapmargin
              Type: number
              Default: 0

              (DEPRECATED) Equivalent to setting $wrap with a negative value.

       write_bcc
              Type: boolean
              Default: yes

              Controls whether NeoMutt writes out the “Bcc:” header when preparing messages to  be  sent.   Exim
              users may wish to unset this. If NeoMutt is set to deliver directly via SMTP (see $smtp_url), this
              option does nothing: NeoMutt will never write out the “Bcc:” header in this case.

              Note: On Debian systems, exim4 and postfix strip BCC headers by default. The above warning applies
              to exim3 users, see /etc/Muttrc.

       write_inc
              Type: number
              Default: 10

              When  writing a mailbox, a message will be printed every $write_inc messages to indicate progress.
              If set to 0, only a single message will be displayed before writing a mailbox.

              Also see the $read_inc, $net_inc and $time_inc variables and the “tuning” section  of  the  manual
              for performance considerations.

       x_comment_to
              Type: boolean
              Default: no

              If  set,  NeoMutt  will  add  “X-Comment-To:”  field  (that contains full name of original article
              author) to article that followuped to newsgroup.

       collapse_all
              Type: boolean
              Default: no

              When set, NeoMutt will collapse all threads when entering a folder.
