Assuming that you already tried using Bellsouth as a smarthost... Can you
post the NDR that you get when using it?

Could you try this? Get the IP address from Bellsouth SMTP servers (i.e.
smpt-mail.bellsouth.com). You can get the IP even using something like ping
smtpserver.bellsouth.com and then read the first line (or use nslookup).
Then setup the smarthost using that IP instead of the servername. Let us
know if it works.
