That's odd.  Bayes, Razor2, DCC work quite well for me.  Check out my

Razor2 caught 83% of the spam, DCC caught 68%, and Bayes got 64%.

Agreed on URIBL and SURBL.  Both of those have good showings in my stats
as well.

I don't swap out the SARE rules.  I use most of them and just let them
run.  My server doesn't see quite enough traffic for it to create a
problem.  They don't catch as much as the net rules, but they do help
out from time to time.
