NAME
       in.comsat, comsat - biff server

SYNOPSIS
       /usr/sbin/in.comsat

DESCRIPTION
       comsat is the server process which listens for reports of incoming mail
       and notifies users who have requested to be told when mail arrives.  It
       is  invoked as needed by inetd(1M), and times out if inactive for a few
       minutes.

       comsat listens on a datagram port  associated  with  the	 biff  service
       specification (see services(4)) for one line messages of the form

	      user@mailbox-offset

       If  the	user  specified	 is logged in to the system and the associated
       terminal has the owner execute bit turned on (by a biff y), the	offset
       is  used	 as  a	seek offset into the appropriate mailbox file, and the
       first 7 lines or 560 characters of  the	message	 are  printed  on  the
       user's  terminal.   Lines which appear to be part of the message header
       other than the From, To,	 Date, or Subject lines are not	 printed  when
       displaying the message.
