ZMAILNOTIFY(1)ZMAILNOTIFY(1)NAMEzmailnotify - retrieve mail headers from post office and
transmit via Zephyr
SYNOPSISzmailnotifyDESCRIPTIONzmailnotify connects to the invoking user's POP post
office and retrieves the From, To, and Subject fields of
waiting messages, and then sends one Zephyr notice per
message to class MAIL, instance POPRET, recipient
<user@realm>, where <user@realm> is the invoking user's
username concatenated with the local Zephyr realm (e.g.
jruser@ATHENA.MIT.EDU).
zmailnotify is intended to be executed by zwgc(1) when
notifications of spooled mail (such as those generated by
zpopnotify(8)) are delivered. By default, these notifica
tions are not delivered, nor are they acted upon. To
receive the notices, you must subscribe to class MAIL,
instance POP, recipient username@realm (see zctl(1)).
Once you subscribe to these notices, by default they will
be simply displayed on your display or terminal by
zwgc(1). To have zmailnotify executed when they are
delivered, you must copy the system default windowgram
description file (/usr/athena/lib/zephyr/zwgc.desc) to
your home directory as filename ~/.zwgc.desc and follow
the directions contained in that file pertaining to MAIL
NOTIFICATION.
zmailnotify only retrieves four headers at one time in
order to reduce the competition for the mailbox lock on
the post office. If more than four mail messages are
waiting, zmailnotify will only retrieve the four most
recent mail headers.
To check for mail already waiting when you log in, use the
standard MH program msgchk(1).
BUGSzmailnotify only sends notification of mail which appears
to be unique. Uniqueness is determined by comparing the
To:, From:, and Subject: fields of the message with the
last checked mail message; if the three fields match
exactly, the new message is not considered unique. The
To:, From:, and Subject: fields of the last message are
stored in the file $HOME/.maillock.
