Spam Filtering

[rbutturini at epictn.com (Russell Butturini)]

We sell and install a lot of Barracuda spam firewalls (which at their core are spamassassin with a fancy web frontend). 
 I've found that after proper tuning, they work extremely well.  If you don't have time to manage your filtering and 
want them to manage updates, users to manage their quarantines, etc.  It's a pretty good solution.

We use amavis/spamassasin/clamAV for our gateway. We are using the
openprotect.com rules channel for rules with a great amount of
success.

We are also using postgrey to do greylisting of emails but that is not
as effective anymore, creates more complaints about delaying mail than
stopping SPAM.
