To receive the notices, you must subscribe to class MAIL, -instance POP, recipient username@realm (see \fIzctl\fR(1)). -Once you subscribe to these notices, by default they will be simply -displayed on your display or terminal by -.I zwgc(1). -To have -.I zmailnotify -executed when they are delivered, you must copy the system default -windowgram description file (\fI/usr/athena/lib/zephyr/zwgc.desc\fR) to your home -directory as filename -.I ~/.zwgc.desc -and follow the directions contained in that file pertaining to -.B MAIL NOTIFICATION. -.PP -.I 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, -.I zmailnotify -will only retrieve the four most recent mail headers. -.PP -To check for mail already waiting when you log in, use the standard MH -program -.I msgchk(1). -.SH BUGS -.I zmailnotify -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 -.IR $HOME/.maillock . -.SH FILES -$HOME/.maillock -.SH SEE ALSO -msgchk(1), zctl(1), zephyr(1), zwgc(1), zhm(8), zephyrd(8), -zpopnotify(8), popd(8) -.br -Project Athena Technical Plan Section E.4.1, `Zephyr Notification -Service' -.SH AUTHOR -.PP -Robert S.
