I have 5 different email addresses all listed in Thunderbird. They are all selected to forward/show/store email in one account. But my old messages are still in the other individual accounts. Many are duplicating mail in their "inbox" and in an "all mail" folder as well as being directed to the 'master' account. How do I stop the duplication, cleanup old mails & duplicates?
