The way I did this, I created a "Junk" queue (I think it mightve been there
by default actually).  We use spamassassin for spam filtering, and I created
a PostMaster Rule that checks for the presence of the SpamFlag="YES".. If
its there, it sets the destination queue to Junk.

PS: make sure your mail server supports greylisting; enabling greylisting
cut our spam down by 90%.

A company I help run offers Spam Filtering with a Symantec appliance for
$50/year.  Your email goes through one of two boxes and filters out 97% of
spam with less than one false positive per 1 million emails analyzed.  It
does let some Nigerian fraud emails through, but that's about it.  I cut my
own spam from 200-300 a day down to about 5 a day.

$50/year is really really cheap.

What we have:

Setup is easy -- you point your MX DNS records to us, we deliver the mail
to your mail server as normal.  Plus we hold your mail if your mail server
goes down.
