This behavior is still present in the most current versions (note message date) of Thunderbird on Ubuntu and SeaMonkey on Windows 7. It does appear to be an issue when applying after the fact to IMAP and POP mail. Someone commented about a search function for AOL. Every webmail account I have, including AOL, has a search function. Many of these *custom* headers are standard headers. The best workaround, in my opinion, is to simply add common headers to future builds. This can also be an issue because occasionally the mail filters cannot find the folder the message is to be moved (another bug?). In my mind, X should imply custom headers since that is the recommended standard. All other common headers should be considered standard.
A suggest list, including those already listed, should contain Authentication-Results, BCC, CC, Content-Type, Content-Transfer- Encoding, Date, Delivered-To, DKIM-Signature, DomainKey-Signature, From, List-Id, List-Subscribe, List-Unsubscribe, Mailing-List, Message-ID, MIME-Version, Precedence, Received, References, Reply-To, Return-Path, Sender, Subject, To. I'm sure this is not a comprehensive list. Also, some of these may be meaningless and some starting with X might be added. However, the person working on this bug will make the final decision when editing the code. Please offer further suggestions so that we may come to an agreement. I don't think this work around will add bulk or slow down mail. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/119899 Title: After-the-fact Filters on custom header won't match for IMAP messages Status in Mozilla Thunderbird Mail and News: Confirmed Status in “thunderbird” package in Ubuntu: Triaged Bug description: Binary package hint: thunderbird Message filtering appears to be broken on Thunderbird 2.0.0.4~rc1-0ubuntu1 in Gutsy with IMAP. I created a filter for the warthogs list and it would not move the messages from my inbox to the folder I had created. It also did not put anything into the filter log. I tried using the Thunderbird on Feisty with my laptop and it worked fine when using the same settings. Chris Jones mentioned he also noticed the same or perhaps a similar issue today.
