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 0600 will be used
       (on filesystems that support it).  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.

       The  -file  switch  does not support use of standard input.  Instead, the rcvstore command
       can be used to incorporate mail from the standard input stream.

       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 -port switch specifies the  port  name
       or number used to connect to the POP server.  If unspecified the default is “pop3”.

       To  specify  a  username  for  authentication  with the POP server, use the -user username
       switch.  The credentials profile entry in the mh-profile(5) man page describes the ways to
       supply a username and password.

       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,  as
       described  in  the  mh-profile(5) man page).  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.

       /var/mail/$USER     Location of the system mail drop.

PROFILE COMPONENTS

       Path:               To determine the user's nmh directory.

       Msg-Protect:        To set mode when creating a new message and audit-file.
       Unseen-Sequence:    To name sequences denoting unseen messages.

DEFAULTS

       +folder             defaulted by “Inbox” above.
       -noaudit
       -changecur
       -format             As described above.
       -nosilent
       -nosasl
       -truncate           If -file name not given, -notruncate otherwise.
       -width              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.
