That is why they have an entry at rfc ignorant...
http://www.rfc-ignorant.org/tools/lookup.php?domain=att.com
However, (and I really don't know) it is possible that the only valid
regular user mail uses .net instead of .com addresses??
att.com is net is not listed and does accept them.
220 worldnet.att.net - Maillennium ESMTP/MULTIBOX mtiwgwc14 #1081
helo example.com
250 worldnet.att.net
mail from: <>
250 ok
...
With a former company that I worked for, their use of .net was only
internal. Any mail being sent out used .com version of the domain. The
hostnames using .net entries didn't even have dns entries on the outside.
