I surely would expect that, otherwise it wouldn't make sense to use it. As 
BarricadeMX seems to be a combination of the snertsoft milters and some 
other techniques in one piece of software there *should* be better 
ressource usage *and* better protection. My point was that the original 
poster compared that with an almost unprotected system and was very 
impressed. He *should* be very impressed, if not the system wouldn't be 
worth much. My point is not against BarricadeMX at all, I'm confident it 
works very good and is worth the money.
A point I didn't mention is that I think that you still need MailScanner 
and a quarantine. My point-of-view is that users should be bothered with 
as few spam as possible. You can't achieve that with blocking all high 
scoring spam (although I have to admit that most detected spam is high 
scoring). There's always a "middle range" where the false positive rate is 
too high to just reject them - and I really would not want to just tag 
them and send on. Not to mention the other things that MailScanner can do.
