Why are you still using smtp.sbcglobal.net when AT&T/SBC has
been warning its customers for about a year already that the old
servers and old settings are going away?
Use the new server names and settings shown here:
http://helpme.att.net/article.php?item=10918
Scroll down to the bottom of that page where the manual settings are.
Also make sure "My server requires authentication" is checked.
