1 month ago I think like always with this type of request is that you need a filter to run automatically in a folder that is different from Inbox - which is something that the underlying architecture of Thunderbird doesn't support directly. The filter service is part of the compiled part of Thunderbird (it runs in C++) and cannot be modified via an Add-on. So the best place to ask for a fundamental change like this is the Thunderbird bugzilla:
https://bugzilla.mozilla.org/enter_bug.cgi?product=Thunderbird
And then select Filters from Component. Possible existing matches:
Filters should be per-Folder, not per-Account - Filter on non-Inbox folders Feature Request: Automatically Run Filters on All Folders, Not Just the Inbox
Feature request I have some filters that move things into other folders and I want to keep those emails for a time but then once they are aged, I would like to move them again or delete them depending on the folder. I don't need this to trigger by an event necessarily but perhaps have it run periodically without my having to go into each folder and run it manually.
I would be willing to write a macro or program to do that sort of thing but I don't actually know how to do that for Thunderbird and don't really have the time to teach myself that new trick at the moment. If anyone has a link to a tutorial on how to learn such a thing fast, I'm interested.
