I've been implementing an aggressive spam/virus filtering forward MX server. Currently, I am using SpamAssassin, Razor, DCC, Amavisd-New, yadda yadda and we're stopping a huge amount of shit. Currently, I'm blocking about 1,000 spam messages a day who's score is >=10.0 and marking who knows how many (actually i do know, i just dont have it handy) messages as spam. It's all running on a dual PIII 1ghz box w/ 1gb ram and slack 9.1
My next planned prong in the fight for spam was to start blocking troublesome address blocks with iptables. I've written a quick perl script that generates source IP info for our spam. My question, NO, questions are: 1.) Will having large IPTables rulesets cause a significant performance hit? I have plenty of resources to spare as all the crap I have running on it now aren't taxing it much. Facts and educated opinion appreciated. 2.) Is there a port of OpenBSD's spamd available for Linux? I've searched on Google with no luck. Are there any other slick tarpitting solutions for Linux? If I could find something, I'd probably do this in leiu of the iptables route, just to screw with the spammers and help other folks on the net.
