Not as far as I can tell. If it really is that easy to block ports on an
individual user basis, you can just as easily block them at your router as
you can at your mail system. Or perhaps it is even easier to do at the router
than at the mail system. As for monitoring, you can also just monitor their
port 25 activity instead of couting the number of messages they have queued
at your relay.
