Category: mail delivery Group: Mailman 2.2 / 3.0 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Julian Ladisch (julianladisch) Assigned to: Nobody/Anonymous (nobody) Summary: FORGED_MUA_THEBAT_CS: The Bat! and Spamassassin Initial Comment: The mail user agent "The Bat!" creates header lines like this if there is some non-ascii character like a umlaut (ä): X-Mailer: The Bat! (v2.00) Content-Type: text/plain; charset=ISO-8859-15 "The Bat!" never puts quotes around the charset. Mailman's Decorate.py changes this to: X-Mailer: The Bat! (v2.00) Content-Type: text/plain; charset="iso-8859-15" Spamassassin has a spam detection rule that triggeres if X-Mailer contains "The Bat!" and there are quotes around the charset. The rule is named FORGED_MUA_THEBAT_CS and is located in rules/20_ratware.cf http://svn.apache.org/repos/asf/spamassassin/tags/spamassassin_release_3_2_3... My patch renames X-Mailer to X-X-Mailer. That prevents triggering the rule without information loss. I've tested the patch that applies to 2.1.7 and it works for me. I havn't tested the patch for trunk (8228). ----------------------------------------------------------------------

Message: Logged In: YES user_id=561017 Originator: YES Mailman delivers the email to all subscribers of the mailing list. Spamassassin runs on the mail servers of the subscribers. I don't have access to the configuration of these mail servers, so I cannot nullify that spamassassin test. For discussing improvements to spamassassin regarding this bug please use http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5658 However, as many sites don't update spamassassin frequently we should consider patching Mailman as well. ---------------------------------------------------------------------- Comment By: Mark Sapiro (msapiro) Date: 2007-09-28 01:18 Message: Logged In: YES user_id=1123998 Originator: NO If you really want to nullify this spamassassin test, why not just put score FORGED_MUA_THEBAT_CS 0 0 0 0 in the appropriate spamassassin user_prefs file? ---------------------------------------------------------------------- Comment By: Julian Ladisch (julianladisch) Date: 2007-09-27 16:02 Message: Logged In: YES user_id=561017 Originator: YES File Added: Decorate.py-8228.diff ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=300103&aid=1803606&group_id=103
