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.
