msgchk - check for messages
msgchk [-date] [-nodate] [-notify all/mail/nomail]
[-host hostname] [-user username] [-kpop]
[users ...] [-version] [-help]
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.
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.
The default is for msgchk 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 contain-
ing 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
machine mypopserver login mylogin password mypassword
This ".netrc" file should be owned and readable only by you.
For debugging purposes, there is also a switch `-snoop', which will
allow you to watch the POP transaction take place between you and the
If nmh has been compiled with KPOP #defined, the `-kpop' switch will
allow msgchk to use Kerberized POP rather than standard POP3 on a given
invocation. If POPSERVICE was also #defined to "kpop", msgchk will be
hardwired to always use KPOP.
