DESCRIPTION

       Inc incorporates mail from the user's incoming mail drop into an nmh folder.  If the mail drop is a file,
       it  can  be  in  mbox or MMDF format.  If the mail drop is a directory it will considered to be a Maildir
       format mail drop.

       You may specify which folder to use with +folder.  If no folder is specified, then inc  will  use  either
       the  folder  given by a (non-empty) “Inbox” entry in the user's profile, or the folder named “inbox”.  If
       the specified (or default) folder doesn't exist, the user will be queried prior to its creation.

       When the new messages are incorporated into the folder, they are assigned numbers starting with the  next
       highest  number  for  the  folder.   As  the  messages  are  processed, a scan listing of the new mail is
       produced.

       If the user's profile contains a “Msg-Protect: nnn” entry, it will be used as the protection on the newly
       created messages, otherwise the nmh default of 0644 will be used.  For all subsequent operations on these
       messages, this initially assigned protection will be preserved.

       If the switch -audit audit-file is specified (usually as a default switch in the profile), then inc  will
       append a header line and a line per message to the end of the specified audit-file with the format:

            <<inc>> date
            <scan line for first message>
            <scan line for second message>
            <etc.>

       This  is  useful  for keeping track of volume and source of incoming mail.  Eventually, repl, forw, comp,
       and dist may also produce audits to this (or another) file, perhaps with “Message-Id” information to keep
       an exact correspondence history.  “Audit-file” will be in the user's nmh directory unless a full path  is
       specified.

       Inc  will  incorporate  even  improperly formatted messages into the user's nmh folder, inserting a blank
       line prior to the offending component and printing a comment identifying the bad message.

       In all cases, the user's mail drop will be zeroed, unless the -notruncate switch is given.

       If the profile entry “Unseen-Sequence” is present and non-empty, then inc will  add  each  of  the  newly
       incorporated messages to each sequence named by the profile entry.  Inc will not zero each sequence prior
       to adding messages.

       The interpretation of the -form formatfile, -format string, and -width columns switches is the same as in
       scan.

       By  using  the  -file  name switch, one can direct inc to incorporate messages from a file other than the
       user's maildrop.  Note that the name file will NOT be zeroed, unless the -truncate switch is given.

       If the environment variable $MAILDROP is set, then inc uses it as the location  of  the  user's  maildrop
       instead  of  the  default  (the  -file  name  switch still overrides this, however).  If this environment
       variable is not set, then inc will consult the profile entry “MailDrop” for  this  information.   If  the
       value  found  is not absolute, then it is interpreted relative to the user's nmh directory.  If the value
       is not found, then inc will look in the standard system location for the user's maildrop.

       The -silent switch directs inc to be quiet and not ask any questions at all.  This is useful for  putting
       inc in the background and going on to other things.

   Using POP
       inc  will normally check local mail drops for mail, as covered above.  But if the option “pophost” is set
       in “mts.conf”, or if the -host hostname switch is given, or if the $MAILHOST environment variable is set,
       then inc will query this POP service host for mail to incorporate.  If $MAILHOST  is  set  and  -host  is
       specified as well, the commandline switch will override the environment variable.

       The  default  is  for  inc to assume that your account name on the POP server is the same as your current
       username.  To specify a different username, use the -user username switch.

       When using POP, you will normally need to type the password for your account on the POP server, in  order
       to  retrieve  your  messages.   It  is  possible  to  automate  this  process by creating a “.netrc” file
       containing your login account information for this POP server.  For each POP  server,  this  file  should
       have  a line of the following form.  Replace the words mypopserver, mylogin, and mypassword with your own
       account information.

            machine mypopserver login mylogin password mypassword

       This “.netrc” file should be owned and readable only by you.

       If passed the -proxy command switch, inc will use the specified command to establish  the  connection  to
       the POP server. The string %h in the command will be substituted by the hostname to connect to.

       If  inc  uses  POP,  then  the -pack file switch is considered. If given, then inc simply uses the POP to
       packf the user's maildrop from the POP service host to the named file.  This switch is provided for those
       users who prefer to use msh to read their maildrops.

       For debugging purposes, you may give the switch -snoop, which will allow you to watch the POP transaction
       take place between you and the POP server.

       If nmh has been compiled with SASL support, the -sasl switch will enable the use of SASL  authentication.
       Depending  on  the SASL mechanism used, this may require an additional password prompt from the user (but
       the “.netrc” file can be used to store this password).  The -saslmech switch can  be  used  to  select  a
       particular SASL mechanism.

       If  SASL  authentication  is  successful,  inc  will  attempt  to  negotiate a security layer for session
       encryption.  Encrypted traffic is labelled with `(encrypted)' and  `(decrypted)'  when  viewing  the  POP
       transaction with the -snoop switch.

FILES

       $HOME/.mh_profile          The user profile
       /etc/nmh/mts.conf          nmh mts configuration file
       /var/mail/$USER            Location of mail drop

PROFILE COMPONENTS

       Inbox:               To determine the inbox, default “inbox”
       Folder-Protect:      To set mode when creating a new folder
       Msg-Protect:         To set mode when creating a new message and audit-file

DEFAULTS

       `+folder' defaulted by “Inbox” above
       `-noaudit'
       `-changecur'
       `-format' defaulted as described above
       `-nosilent'
       `-truncate' if `-file name' not given, `-notruncate' otherwise
       `-width' defaulted to the width of the terminal
       `-nopack'

CONTEXT

       The  folder into which messages are being incorporated will become the current folder.  The first message
       incorporated will become the current message, unless the -nochangecur option is specified.   This  leaves
       the context ready for a show of the first new message.

BUGS

       The  argument  to the -format switch must be interpreted as a single token by the shell that invokes inc.
       Therefore, one must usually place the argument to this switch inside quotes.
