in.comsat(1M)
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 mes-
sages 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 char-
acters 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.
