In mail on the left hand side of the window under mailboxes, I have all of my different email accounts then I have a line that says "ON MY MAC" Under it is a folder that says import, and then in the import folder I have a folder that I imported.
The question I have is this "ON MY MAC" is duplicated. So I have 2 on my macs???
Great tip, worked great. DO NOT try to DELETE one of the duplicate on my mac folders. It will delete all of them permanently. Made that mistake on my macbook pro.
