This is extremely frustrating. Emails keep coming back regardless of if I move/delete them via my Mac or iPhone. Most of the times a DELETE or MOVE via webmail stays deleted or moved. Recently, I even have to delete/move some of them on both the iPhone and MAC. Aaaaaaahhhhhhhh! I find the same thing happening with 3 GMAIL accounts as well as two accounts hosted by GoDaddy, so I'm guessing the problem in on the Apple side. Some people have suggested I uncheck the "Use IDLE command if the server supports it" checkbox. I did, to no avail. Any clues, pointers or suggestions?
