I have also had the same issue on Bellsouth. It worked Friday night (2/19/10) but not today. I checked settings and tried webmail (which works) but stumbled upon a page that said Bellsouth would not let me check or change any information on my account because their servers were down for maintenance. Anyone else tried that route? I really think it is Bellsouth/AT&T doing something to fix something that wasn't really broken.

Seems to be working now using (mail.bellsouth.net) email server, additional outbound servers and bellsouth/AT&T DSL service. NO more immediate bounce back.

You might try one of these links:
Perhaps you might find something useful there. In any case, the problem
is not Outlook, a rarity I admit, but rather with the downstream ISP.
