Ah, outgoing mail? Then I'd strongly recommend taking a look at the DCC
(http://www.rhyolite.com/dcc/)

The description on the site above is how to set it up as an inbound bulkmail
checker, exchanging checksum floods with peering dcc sites ... but you can
set it up to be standalone as well.

Or you could do what we do - find the account and freeze it if it starts
sending more than a certain number of emails per 10 minutes.
