Just a couple of corrections to two of the posts in this thread:

I think you are mixing/confusing SORBS and MAPS. MAPS was bought by
Trend and is run as a service based on subscription fees. SORBS is
whatever it is. If you don't like SORBS, that's great, but don't tar
Trend with that brush.

Actually, that's not true. I don't want to get into an argument about
"single most effective," but I can guarantee that using a good
reputation service will block more than 50% of the incoming spam to your
network. The leading ones normally hit the 80% range.
In fact, many of the popular anti-spam appliances are completely
miserable at the content filter end which is applied post-reputation
service; without reputation filtering, they wouldn't be worth using.
(My information is based on monthly testing of anti-spam appliances we
have conducted for the past 5 years. For example, this month we are
looking at 43 different appliances and 25 reputation sevices)
