| comsat | [ -l] | 
comsat is the server process which receives reports of
  incoming mail and notifies users if they have requested this service.
  comsat receives messages on a datagram port associated
  with the “biff” service specification (see
  services(5) and
  inetd(8)). The one line messages
  are of the form:
user@mailbox-offsetIf 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” or “Subject” lines
    are not included in the displayed message.
comsat program supports this option:
-l-l option turns on
      syslogd(8) log

  consults:
comsat command appeared in
  4.2BSD.
Users should be notified of mail which arrives on other machines than the one to which they are currently logged in.
The notification should appear in a separate window so it does not mess up the screen.
comsat runs as root so that it can open
    the user's maildrop.
