Since I got an external program (imapfilter) modifying my imap folder, thunderbird keeps loosing track of new messages. Messages are moved upon arrival in sub-folders, making Thunderbird unable keep tracking them - therefore I have no clue which folders to look for new messages, and newly created folders (even I subscribe them after creation) does not show up until I restart the mail client.
Is there any extension or setting for Thunderbird which I could use to trigger re-scanning my folder tree?
Please don't waste time on advices like
even folders can be created in the background, without Thunderbird would know it has been created.
