Hello Sandy, Just want to thank you for all of your help and suggestions on getting Postfix running. The ultimate problem was with the configuration of spamassassin and mailscanner. Best regards, James

Hello James, good to know that your server is up and running again. If you would like we can tune the configuration to reject most of the spam right away without the need to process them with mailscanner. (^-^) I usually reject about 90-95% of attempted spam deliveries with Postfix checks alone. It saves a lot of resources and even more important it saves the time to check them by hand, which is necessary even when spamassassin already marks them as spam (it's a bad idea to delete mails automatically). It's also advisable to set up a kind of report or log review, so you know what happened on your system during the day. pflogsumm and mailgraph for example are easy to set up and give you a fast overview what happens on your system.

greylisting I presume?
Not yet, I am still testing greylisting on my server at home. It's the cumulative result of HELO-, client- and sender-checks, RBLs and a bit of tuning, a smaller percentage of spam is rejected due to message id checks. What kind of checks are usable depends on your situation, of course. As a company I can afford to apply stricter checks than a hosting ISP, for example. Now, with Postfix 2.3 and Milter, I'll probably use domain key checks in addition to greylisting soon. Since there seems to be a bit of general interest, maybe we can put together some guide lines and experiences about fighting spam with Postfix, so people can find it through the archives.
