Name
       comsat - biff server

Syntax
       /etc/comsat

Description
       The command is the server process which receives reports of incoming mail and notifies users if they have requested this service.  The com-
       mand is invoked by when it detects an incoming packet on the datagram port associated with the ``biff'' service specification.  For further
       information, see The command reads the packet, which is a one line message 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 included
       in the displayed message.

Restrictions
       The message header filtering is prone to error.

Files
       Information about who is logged on to which terminals
