NAME

comsat − The biff server

SYNOPSIS

comsat

DESCRIPTION

The comsat server receives reports of incoming mail and notifies users who request this service.  comsat is invoked by the inetd(8) daemon when it receives messages on a datagram port associated with the biff(1) service specification in /etc/services(4).  The datagram contains a 1-line message of the form:

user@mailbox-offset

If the user specified is logged in and the associated terminal has the owner execute bit turned on (with biff y), offset is used as a seek offset into the file named in mailbox.  The first 7 lines or 560 characters of the message are printed on the user’s system.  The message excludes mail header lines other than the From, To, Date, or Subject lines.
