> I have postfix 2.3.3 installed and have just found some info on > Anvil(8) which looks like it should be good as part of my anti-spam implementation. I can see anvil in /usr/libexec/postfix/ but when i enable the config within main.cf smtpd_error_sleep_time = 1s and grep on maillog there's no entry for anvil - its as though it isn't > compiled or something. Anyone know how to get it up and running?
While you're welcome to try what you want, it looks like you're over-optimizing the wrong thing. Spammers don't care about your server rate limits. Most spam is spread out with one or two emails coming from thousands of zombies, which Anvil won't notice. It's rare (at least from what I've seen) to get more than a couple of dozen messages at one time from a single infected IP. In the end, all you'll end up with is a weird server that causes problems with legitimate email and doesn't stop spam. I'd suggest rejecting anybody with no reverse DNS, and if you're feeling adventurous, some regular expressions to reject dynamic addresses you don't want to talk to, then checking a few carefully selected RBLs. Give whatever gets though to SpamAssassin. Terry -- CNY Support, LLC Web. Database. Business http://www.cnysupport.com
