I just got my first mac a few days ago. I think I'm doing pretty well with the changes, but I can't make anything send out of my email. Sent messages sit in my outbox while the "send" file just shows a turning black circle as though it is trying to send. I can click "Window" and "Activity" and click on the stop sign to make it stop trying to send, but then it still won't send the message when I re-try. I've tried deleting the messges out of the outbox and starting all over. I've tried quitting mail and pulling it back up. What could be the issue? Thanks!
