Is there any news on this bug? I have just run into the same problem, although I am manually running rules on messages after I have read them (to automatically sort them into the correct folders.) I'm trying to sort on the List-Id field, but wiping all the .msf files didn't help. Enabling offline folders on the Inbox then compacting all folders didn't work either. My customHeaders field says:
user_pref("mailnews.customHeaders", "DomainKey-Signature: Received: List-Id"); So I'm not sure whether it's missing a trailing colon there or what. But either way, even though the message is visible in the preview pane when I run the filter, the extra headers still seem to be ignored. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/119899 Title: After-the-fact Filters on custom header won't match for IMAP messages -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
