Spam. [tool to automatically filter out most spam]

[Bryan Andrews]

If you haven't seen SpamAssassin yet I suggest you'll take a look. 

http://spamassassin.taint.org/

Very useful! Ever sense I set it up on my colo linux server I haven't
had any spam at all to any of my domains.  I just recently setup a
linux box with spam assassin to simply filter out spam and redirect it
to the real SMTP server at work.  From my experience it's enterprise
ready.

"We're on the threshold of a whole new system. The time where
accountants decide what music people hear is coming to an
end. Accountants may be good at numbers, but they have terrible
taste
in music. I don't know how I'm going to get paid, but I'd rather go
out into the brave new world than live with dinosaurs that are far
too
big for their boots." - Keith Richards - Rolling Stones Guitarist
