I'm using Ubuntu 10.10 and Thunderbird 3.1.7 and I have a comparable bug. In the filter windows, I created a new header : Reply-To. I then tried to use it in a filter and it doesn't work correctly. The attachment 502220 in the comment 109 are the file I used to do my tests.
All my tests were done after the both messages were received. Each time I put the message in the Inbox folder before to run the filters. I try to filter the both messages in the attachment by three ways : with the Execute button in the filter windows, with Tools --> Execute filters on the message and with Tools --> Execute filters on the folder. When I applied the filters on the message, nothing happened ! When I used the two others ways, the message which begins by "Filter works :" was well filtered, so moved in the folder I chose (Ubuntu in this case). I also try this filter on other messages and it doesn't work. In comparison, my other filters (on non-personally created headers such as from or to) works fine with the three ways. -- 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
