Without answering a specific question, I will just provide you live
data for just one user. Me. As I just got URIBL's working, I'm still
monitoring all the spam, so I can say that in the 2542 message that
came in in the last 24 hours there were 0 false positives and only 3
false negatives (all of which passed because of AWL, which suffered a
lot of bad training. It's learning, though.)
I don't know about these amazing new spammer tricks (that's irony, by
the way), but it SA sure does work against what's actually out in the
wild.
