  Main Topic: Mail Server setup and configuration, with SPAM filtering
Our speakers are Bill Allie, and Rick Harding

Spam has become a huge problem, clogging up our inboxes and the
internet as a whole. there are estimates that 80-90 percent of all
email is unwanted, unsolicited junk mail (spam). there's a number of
ways to combat this problem. Our first speaker, Bill Allie has recently
rebuilt his Linux based mail server and is going to tell us about
setting up a basic mail server with SPAM and virus filtering using
postfix (why postfix and not sendmail, he'll tell us), greylisting and
segregator.

His goal was to stem the flow of junk mail (both SPAM and viruses) that
his server had to handle. He'll discuss what he did to filter out the
junk using open source tools. The discussion will cover the selection
and configuring of the Mail Transport Agent (MTA), how to limit spam
using SMTP policies, header restrictions, spam filtering software, and
virus blocking software.

Rick Harding will add his input on using amavisd as the filtering end
of the solution as well as some information on tweaking spamassassin.
