I have set up a mail server using the Virtual Users And Domains With Postfix, Courier And MySQL (Fedora Core 5) guide - working great for the last few months, then I noticed something yesterday. Emails coming in from addresses on the auto white list are having their spam score INCREASED instead of Decreased - consequently they are being marked as spam when they should not. Here is the relevant part of the mail header for the email that alerted me to the problem: Code: X-Virus-Scanned: amavisd-new at localhost X-Spam-Flag: YES X-Spam-Score: 4.646 X-Spam-Level: **** X-Spam-Status: Yes, score=4.646 tagged_above=2 required=4 tests=[AWL=4.691, BAYES_00=-2.599, FORGED_RCVD_HELO=0.135, HELO_EQ_AU=0.377, HOST_EQ_AU=0.327, HTML_40_50=0.496, HTML_MESSAGE=0.001, MIME_BASE64_NO_NAME=0.224, RELAY_IS_203=0.994] X-Spam-Report: * 1.0 RELAY_IS_203 RELAY_IS_203 * 0.3 HOST_EQ_AU HOST_EQ_AU * 0.4 HELO_EQ_AU HELO_EQ_AU * 0.1 FORGED_RCVD_HELO Received: contains a forged HELO * -2.6 BAYES_00 BODY: Bayesian spam probability is 0 to 1% * [score: 0.0000] * 0.5 HTML_40_50 BODY: Message is 40% to 50% HTML * 0.0 HTML_MESSAGE BODY: HTML included in message * 0.2 MIME_BASE64_NO_NAME RAW: base64 attachment does not have a file * name * 4.7 AWL AWL: From: address is in the auto white-list AWL aside, the mail is given a score of -.1, which is fine. but the 4.7 added by the AWL bumps it over the spam threshold. How can I fix this?
