MSGCHK(1)

NAME
msgchk - check for messages

SYNOPSIS
msgchk [-date] [-nodate] [-notify all/mail/nomail] [-nonotify all/mail/nomail] [-host host] [-user user] [-apop] [-noapop] [-rpop] [-norpop] [users ...] [-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. If the local host is configured as a POP client, or if the `-host host' switch is given, msgchk will query the POP service host as to the status of mail waiting. If the `-user user' switch is not given, then the current username is used. Normally, msgchk will prompt for a password to use. However, if the `-apop' switch is given, msgchk will generate authentication credentials to provide for origin authentication and replay protection, but which do not involve sending a password in the clear over the network. Otherwise, if the `-rpop' switch is given, then msgchk will try to use a "trusted" connection (ala the BSD r-commands).
