How to stop duplicate emails?
Whenever I get an email to my Gmail account or my Outlook account (and forwarded to my default ISP home email), it's duplicated. The two emails might show up as much as 20 minutes apart, but they're always time-stamped identically. Since I have a hunch that ggl and ms wouldn't have the same problems, I feel pretty strongly this is a Thunderbird issue.
My default email is not a problem.
What are the exact steps I should take to eliminate this duplication?
Updated Mac OS, IMAP

There's a particular issue with Gmail which may be part of your problem. Unlike many email providers (and email clients like Thunderbird) Gmail doesn't use mail folders: it has labels instead. Their idea is that you can have more than one label for the same message - 'family', 'important' or whatever. All incoming mail is labelled 'inbox', obviously. But it also receives the 'all mail' label because that applies to everything in your Gmail account. When Thunderbird retrieves your Gmail messages it takes a 'label = folder' approach. So mail labelled 'inbox' goes into your Thunderbird Inbox. But Thunderbird will also find the same message with the 'all mail' label, so it downloads that as well. The solution is to have Thunderbird not subscribe to the 'all mail' label.
