We were running mail on a dual P3-500 using spamc to connect to spamd on a P3-550. The only problems we would have were when the spammers who would bcc the same spam to 20 people over and over would show up, but even that was bearable. Were you using spamc/spamd? We recently added virus scanning to our mail server, so we upgraded to a dual Athlon 1.6gig with a gig of DDR ram. Fast doesn't even begin to describe it. :) > My question is - is there anything we can do to reduce the load against our > servers while running spam assassin.

I would suggest having a look at mimedefang, and in particular, mimedefang-multiplexor. Like spamc/spamd, it'll keep a persistent copy of spamassassin, but it also does pre-forking (ala Apache), and it seems to be much faster than passing messages around with spamc/spamd. Also, the virus scanning integrates with it. Just yesterday, I tweaked mimedefang to reject any mail that scores over 10, which counts for about 2/3rds of our spam. mimedefang can be found at http://www.roaringpenguin.com/mimedefang If you'd like my mimedefang-filter, just ask.
