I came home yesterday to discover I had received no email so I went to Hotmail and found I did indeed have mail. I checked my settings in preferences and they seemed fine. I rebooted my computer and I still couldn't receive mail although I could send it. I called technical support at my server and they checked it and said the problem was with my mail program. I made an appointment with Apple and then I noticed a short squigly line in mailboxes on the left side of mail right where it tells me the number of emails I have new in my inbox. I clicked on it and it disappeared and lo and behold all my mail came pouring in. What is that squigly line - anyone know?
