As a result of reading this: http://www.spamhaus.org/effective_filtering.html we recently added content filtering using the dnsbl milter. http://www.five-ten-sg.com/dnsbl.html This needed a patch to reap zombies for FBSD, and we also hacked out some code to prevent it from checking the nameservers of the URLs found in the messages; we found that to be a bit overzealous. The install script needed changing, as well. If you're interested, I can send you patches that we used to get it working. They really are hacks though, so I'd rather not post them here. This solution *seems* to be working well for us. YMMV. Cheers, Jason.
