Yes - that is true. In fact I manage to block almost 90% of messages
before hitting Spam Assassin and I've been working on tricks to bypass
Ham around SA as well. So - that's how I can process a million atempted
messages a day with a $2000 computer.


BTW - for those of you buying hardwate - Dual Core Athlon 64 X2 with 4
gigs of ram makes a fine Exim/SpamAssassin box. You get 2 64 bit
processors on one chip that is just plain fast.
