I currently have SpamAssassin set to reject anything over 5.0, but I'm still getting a lot of spam. Are there any other good options? I haven't tweaked SA much, just used mostly the default Debian settings with a few whitelist entries (which are not responsible for the spam). It could be that I'm not running SA properly, if anyone has some quick tips on how to optimise it then I'm interested. I'm not so interested in detailed configuration changes because I don't want to go down the path of SA tweaking and because the server I run has lots of people from different regions and some use of multiple languages so I can't just tweak it for me personally. I guess I could try the Bayes stuff, does that give much of a benefit and how easy is it to setup? CRM-114 is said to be good, does it do things better than SA in some significant way? At this stage I'm even considering challenge-response. I figure if everything below a SA score of 3.0 was let through, everyone who I've ever sent mail to or who I've received good mail from was let through, and everything with a SA score over 5.0 was rejected then there wouldn't be too many challenges sent out (only challenges for unknown senders with scores between 3.0 and 5.0). Also if I do CR I'll set things up so that mail from known good lists (like this one) gets the reply-to added to the whitelist, of course challenges won't go out in response to precedence:bulk mail. Some years ago I ran a CR mail system for about 50,000 users and have memorised the design as well as having a copy of some of the code. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
