FWIW, in a previous role we had a shared web hosting system where this
happened occasionally, so I used iptables to block users from making
outgoing connections on port 25 and then added per-uid rate limits to
the local Exim installation. Each website ran under its own uid.
Solved the problem entirely, with very little work.
