This is not a bug. It is a design decision. If you want to do membership tests (moderation and non-member tests) before header filter rules, you can configure that by putting the following in mm_cfg.py. GLOBAL_PIPELINE.remove('Moderate') GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('SpamDetect'), 'Moderate') You could also address this with a header_filter_rules rule of the form regexp: ^From:.*\WX@Y\.Z(\W|$) action: discard ahead of your other rules. ** Changed in: mailman Status: New => Invalid ** Changed in: mailman Assignee: (unassigned) => Mark Sapiro (msapiro) -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1625599 Title: sender filter should take precedence over spam filter To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1625599/+subscriptions
