IN.COMSAT(8) Maintenance Commands and Procedures IN.COMSAT(8)
in.comsat, comsat - biff server
/usr/sbin/in.comsat
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(8), and times out if
inactive for a few minutes.
comsat listens on a datagram port associated with the biff service
specification (see services(5)) 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.

The message header filtering is prone to error.
The in.comsat service is managed by the service management facility,
smf(7), under the service identifier:
svc:/network/comsat:default
Administrative actions on this service, such as enabling, disabling,
or requesting restart, can be performed using svcadm(8).
Responsibility for initiating and restarting this service is
delegated to inetd(8). Use inetadm(8) to make configuration changes
and to view configuration information for this service. The service's
status can be queried using the svcs(1) command.
