Perhaps ATT is now implementing some anti-spam measure, like DKIM.  I go
through this same hassle when trying to send mail to a yahoo recipient
from my mail server.  The problem with yahoo is that they are still using
DomainKeys instead of the newer DKIM (at least the last time I checked;
perhaps they have since upgraded).

Try a gmail test.  Gmail uses DKIM.  Send an email to a gmail account, and
then examine the headers of the received email (if you receive it).
