Public bug reported: MM3 uses List-Post headers to detect mail loops now, so X-BeenThere can be removed entirely. It makes no sense to detect the MM2 legacy X-BeenThere header in MM3. Most examples currently are in the test suite, however the cook_header.py handler still sets it, and this should be removed. ** Affects: mailman Importance: Undecided Status: New ** Tags: mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/883158 Title: Remove X-BeenThere headers To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/883158/+subscriptions
