Hi guys, this is my first post so be gentle! I have just taken delivery of my first ever mac, and sa far it crushes my old PC from a great height! I am having a spot of bother with the mail app though. When i read my mails and then try to delete them, it goes through the motions, but the next time i open mail all my messages are back and i can't see a way of getting rid of them for good! Is there a magical hidden setting that i need to activate all the best mark.
