SORBS on autopilot?

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)
