AMMS can NOT be used to restrict mail flow. If a user wants to send someone
a 1meg file, and the receiving mailer only accepts <1meg, then the user
will be forced to fragment his message (possibly, by hand) to get it through.
If the user really wants his message sent, as is almost always the case,
he will get it through despite any AMMS limits, making it worthless for
controlling mail flow. In this case, AMMS just frustrates the sender
of the message and makes him have to work harder to get around random
whims of the sysadmin.
