OT SPAM filtering

[Jeff Thies]

I've got a couple of SPAM filters on my mail server. The SPAM load is
building again though.

What is working for you?

I'm thinking of looking at link url's in the message, but don't have a list
of sites that spam.

Cheers,
Jeff

What is working for you?

At work (for roughly 400 users) I've set up spam and virus filtering using
SpamAssassin, ClamAV, Amavisd-new and Jim Seymour's Postfix configuration
hints <http://jimsun.linxnet.com/misc/postfix-anti-UCE.txt>. Results are
very good.

http://www.noctua.org.uk/urlbody/ might give you some clues.

DSPAM: http://www.nuclearelephant.com/projects/dspam/

I keep it behind 17 DNS-based blacklists, because the more I reject at
the network interface, the less I have to chew up my system resources.
That said, I see one or two spams in my inbox per month, tops.

DSPAM absolutely beats the stuffing out of SpamAssassin.

Which ones? I use relays.ordb.org, opm.blitzed.org, list.dsbl.org,
sbl.spamhaus.org, cbl.abuseat.org and dul.snsbl.sorbs.net, but am always
on the lookout for good recommendations.
