Package: mailman Version: 2.1.5-8 Severity: normal Short story: when filtering mails for spam I get a moderation loop.
Long story: When using the 'header_filter_rules' (found in the web interface under 'Privacy Options -> Spam Filter') a moderation loop occurs when spam is detected if a rule like 'X-Spam-Status: yes' (what AMaViS typically inserts when spam is found) points to a 'Hold' target. The mail to ...-owner seems to get spam-scanned again and the informational email to the ...-owner get's 'held', too. This happens up to 50 times until the loop stops. The final mail contains a recursive collection of moderation requests. I believe the problem has just recently been dealt with in a later version of mailman (as you can see I'm using Sarge). The patch is described at http://sourceforge.net/tracker/index.php?func=detail&aid=1405790&group_id=103&atid=300103 while you can find a description of the problem at http://mail.python.org/pipermail/mailman-users/2006-January/048573.html The above patch is meant for version 2.1.7. But I believe the following tinier patch would even fix this issue for Sarge (I can't test it on Sid since this is a production server): --- SpamDetect.py.orig 2006-01-16 14:05:42.000000000 +0100 +++ SpamDetect.py 2006-01-16 14:05:18.000000000 +0100 @@ -103,6 +103,15 @@ if mo: # we've detected spam, so throw the message away raise SpamDetected + # Before we go to header_filter_rules, we exclude internally generated + # owner notification from checking, because 1) we collect headers from + # all the attachments but this will cause matching the filter rule again, + # and 2) list owners may want to check header name / value pair like + # 'Precedence: bulk' which is also generated by mailman.
