email Archive
I also use Thunderbird as my email archive with a lot of sub-files. So I have to move manually all the emails from sent to the correct archive sub-file. Is it possible to address a CC archive to move the sent mails automatically in the correct sub-file?

You could create filters that act on the Sent folder and move messages to subfolders, according to specified rules. The filters would have to be run manually, since filters only run automatically on the Inbox, but it would probably streamline the process (see picture).
