How to get Thunderbird to archive messages automatically

Question

I want Thunderbird 3.1.1 to automatically move old messages to archive. The definition of "old" should vary by folder. E.g., messages in the "Meeting minutes" folder should get archived after 7 days, messages in "newsletters" can get archived after 2 days, but messages in a folder for a course I am taking should not get automatically archived, because I am going to manually move the entire folder to archive once the course is over.

I tried making a filter which moves all messages older than 7 days to an archive folder. It worked when I ran it manually. But I don't know how to make Thunderbird run it automatically once a day on the folder "Meeting minutes".

Any ideas how to do it, with or without filters?

Answer 1

The filters only run automatically for any new incoming mail.

For those that are already sitting in your inbox, you'll have to manually select the folder and run the filters for them.

Try setting up some kind of hotkey for the action, or test out the Run Filters on Folder add-on.

The "Age in Days" filter isn't used for existing sitting mail, but for when the sender has their email timestamps some time in the past or future. It's handy for when you're away on vacation or similar black holes of time and when you get back to your email, you don't want to bother dealing with anything sent during the time you were incommunicado.

So if you got back after a month and can't be bothered reading anything older than yesterday, this is where that "Age in Days" filter comes in handy as the emails being downloaded are filtered away leaving only yesterday and forward to deal with right now.

I managed to do run filters on read emails automatically by assigning a shortcut key to the Run Filters on Folder menu item with the Keyconfig and DOM inspector add-ons in combination with a simple autohotkey (http://www.autohotkey.com/) script running a timer.
