Notifies users of incoming mail.
/usr/sbin/comsat [ -d Directory ]
The comsat daemon is the server that receives reports of incoming mail and notifies users if they have enabled this service with the biff command. Started by the inetd daemon, the comsat daemon is not meant to be used at the command line. The comsat daemon receives messages on a datagram port associated with the biff service specification. The one-line messages are of the form:
user@mailbox-offsetIf the user specified is logged in to the system and has run the biff y command, the first 7 lines or 560 characters of the message are displayed on the user's login terminal. Lines that appear to be part of a message header other than the From: or Subject: lines are not included in the displayed message.
