2nd the Roaringpenguin.com recommendation. We used the open-source
version (MIMEDefang) for years and years. It worked great. Never had the
GUI (+postgres backend) or the advanced spam stuff, but i'd tested it and
liked it.
If you just want a blacklist, spamhaus is the best one out there.
If you intend to go total open source (mimedefang, spamassassin, clamav),
I'll say it's doable but it's almost a full time job keeping up with the
rules and making sure you're watching and defending against the attack du
jour. For spam fighting, it's definitely not set it and forget it.
Depending on your mail volume of course. We ended up going with a
commercial appliance (IronPort).

GUI-fied open source packages (or debian based appliance) for a not-so-bad
price with good support and feeds for rules. Customizable per-domain and/or
per-user configurations, etc. It just works.

I was wondering if anyone has any well-working SPAM filters based on open

been using have worked fairly decently until recently, but fighting SPAM is
always a changing war.
I'm familiar with a lot of the commercial products on the market, but I
want to give Open Source a chance before going 100% commercial. I wouldn't
mind a subscription fee for some sort of signature-based service or
blacklist if there's a good one out there, but I would love to see a good
open source framework to start with.
