I recently got a new iMac and restored it using a Time Machine drive to be identical to my old one. This has all gone pretty smoothly, but for some reason mail says that one of my accounts has five new e-mails, and another one has two. When I receive new e-mails these increment, and when I delete them they decrement, but they only ever go down to five and two. Has anyone else had this problem? If anyone could give me a hint as to how to fix it I would be very grateful.
