Thanks for the ping, Stuart. I have not thought about this for awhile, but jumping from comment 101 to the referenced bug 363238, that bug is only implemented for Thunderbird 19 and later, so the fix would not be in the current shipping product, but would be available in the current beta.
Yet that fix is only automating the workarounds mentioned in bug 101. That is, when you define a new custom header to use in filters, that custom header will only work for future messages unless you rebuild the folder. But the current situation (that is, what works in the current Thunderbird beta) is that when you define these custom headers, then they will work for all messages received after that point. They can work for past messages if you rebuild the folder. Any other functionality is very difficult to implement given the current design of the backend, and is unlikely to get any additional work for the foreseeable future. -- 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.
