NAME
       msgchk - check for messages

SYNOPSIS
       msgchk [-date | -nodate] [-notify all/mail/nomail ] [-nonotify
            all/mail/nomail ] [-host hostname] [-user username] [-sasl]
            [-saslmech mechanism] [-snoop] [users ... ] [-version] [-help]

DESCRIPTION
       The msgchk program checks all known mail drops for mail waiting for
       you.  For those drops which have mail for you, msgchk will indicate if
       it believes that you have seen the mail in question before.

       The -notify type switch indicates under what circumstances msgchk
       should produce a message.  The default is -notify all which says that
       msgchk should always report the status of the users maildrop.  Other
       values for `type' include `mail' which says that msgchk should report
       the status of waiting mail; and, `nomail' which says that msgchk should
       report the status of empty maildrops.  The -nonotify type switch has
       the inverted sense, so -nonotify all directs msgchk to never report the
       status of maildrops.  This is useful if the user wishes to check
       msgchk's exit status.  A non-zero exit status indicates that mail was
       not waiting for at least one of the indicated users.

       If msgchk produces output, then the -date switch directs msgchk to
       print out the last date mail was read, if this can be determined.

   Using POP
       msgchk will normally check all the local mail drops, but if the option
       "pophost:" is set in the mts configuration file "mts.conf", or if the
       -host hostname switch is given, msgchk will query this POP service host
       as to the status of mail waiting.

       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.

       For debugging purposes, there is also a 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.
