ordb.org - they only list servers that technically fail anti-relaying measures.

Does it also cover open proxies? In my limited experience, that's where the majority of spam comes from today. relays.osirusoft.com lists proxies as well, there's of course the monkeys.org lists as well. As for TMDA, how useful is it for stopping dictionary attacks, and spammers just ignoring any 550 and blasting away at your mail server(s)? If TMDA sends out a confirmation request each time, it could easily become part of the problem, and not the solution. -- Juha
