Steve, That is exactly what I am doing at the moment on my secondary MX server. = The secondary Imail server was passing in excess of 200+ messages a day to = the primary Imail server (and that was after stopping about 80% of the total secondary traffic from forwarding using various rules I had set up on = that Imail box. So, figure that I have about 1,000 messages hitting that box = each day.). As of this morning, the IMGate box was rejecting all but about 9 messages (of the initial 1,000) each day that hit the server.
Please keep in mind that this is my SECONDARY MX, so the ham/spam = percentage that hits this server is not at all typical. Almost all mail that flows = to the secondary is spam, which is why 99.1% is being blocked. I suspect = that of the nine messages that made it through the various filter rules, even some of that was spam that was clever enough to have slipped by. Right now, on the secondary MX I am using a combination of IMGate, = various other Postfix rule sets that I have developed (pretty simple = anti-profanity filters for the Subject: line), CLAMAV, F-Prot, MessageSniffer, various RBLs, my own domain-based blacklist at http://www.vantekcommunications.com/spam/ , etc. I have been = experimenting with Postgrey and will be implementing Spamassassin, eventually. Even without Bayesian filtering and all of the other neat do-dads that Spamassassin offers, you can still achieve some good numbers. I'm sure = that Len's advanced scripts stop a lot more as well. If I ever get the $$$ = for my IT budget someday, I will certainly add those as well.
