I'm blocking around 2 million spams a day. Yes - I do sender
verification. I also use Spamhaus. And there are a few dozen other
tricks I use to weed out spam up front. I was already blocking over 95%
of spam up front. I think I'm up o 98% now. So this new trick took a
huge bite out of the remaining spam that I process with Spam Assassin.
Right now I think that most all the messages I run through SA are
nonspam. I'm trying to figure out ways to ID nonspam in ACLs to reduce
SA load.
