The very ancient Unix way of announcing email is called "comsat". It is
implemented by a daemon to which the mailer sends a message (using UDP).
The daemon then writes "you have mail" to the user's terminal if she/he
is logged in. Exim has support for comsat - check the "notify_comsat"
option of appendfile. If you were to write a replacement daemon that
accepted comsat-style messages, Exim can already support you.
Oddly enough, I looked at the comsat code only yesterday and thought "I
wonder if anybody uses this any more?"
