Fighting never ending tide of spam mail can turn into a very frustrating experience if you don't know real tricks of trade. After all, there's a whole lot more to it than simply responding to a (usually bogus) From: address with a peevish complaint!
Here's a fairly extensive overview of resources that will aid you in effectively combatting unsolicited email, showing you possibilities (and, alas, limits!) of your endeavor.
General resources ----------------- The Spamhaus Project features a database tracks known Spam Gangs, Spam Support Services and providers who keep organized spamming alive by knowingly hosting stealth spamming services on their networks.

Spamex takes a similar approach, offering disposable email addresses as a measure to counter spam. It doesn't bother with sophisticated spam filters, though - minute your Spamex address receives spam, simply nuke it and get a new one.

Spam filters ------------ Webmasters running their own mail server may be interested in The MAPS Relay Spam Stopper, a queryable DNS-based database of spam-relaying mail servers. You can configure your server to utilize their list if you want to refuse mail from these types of servers. < http://work-rss.mail-abuse.org/rss/ >
The same site offers Realtime Blackhole List (RBL). This is a system for creating intentional network outages ("blackholes") for purpose of limiting transport of known-to-be-unwanted mass e-mail. The RBL is a subscription-only system, working in such a manner that no one is denied connectivity to a non-RBLSM-subscriber. < http://mail-abuse.org/rbl/ >
