Okay this is my problem that just started happening this morning. When I go and get my mail it retrieves it fine and even makes a chime telling me I have picked it up, but does not show any new messages. I have re-started Mail several times, restarted the iMac once and somewhere there is 3 new messages, a couple are important, it showed that it downloaded to the computer, but nothing shows up in my Inbox. Has anyone ever had this happen? I have the program set to delete the server after pick-up, so if the messages are on my computer I don't know where they are because they won't show up. I love my Mac because it does not cause many problems, but times like this makes me irrate!
