MSGCHK(1)MSGCHK(1)NAMEmsgchk - check for messages
SYNOPSISmsgchk [-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-pro‐
file(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.
