Some POP3 servers have the ability to broadcast "bulletins" - you write
a mail, whack it into the configured bulletin directory, and when the
user connects to get their mail it checks to see if they have seen the
bulletin or not, and if not delivers it with the rest of their mail.

The cool thing about this is that the mail is never stored in each
user's spool (in fact, it never goes via the MTA), so it scales very
well.

HTH,
