I'm not from AT&T, but that page contains three errors and three "What to do"
sections. The section referring to RFC 2317 is for DNS errors:
“550 Error. Blocked for status: <unknown sender>”: This error indicates that no
identifying information has been entered into the DNS (Domain Name System) for
this sending system. The AT&T Worldnet mail system, like many others, does not
accept messages from mail systems with no DNS records.
The "Spam complaint" section has a different "What to do:"
What to do: Ask the administrator of your mail system to contact us through our
System Administrators' page and provide the information we need to investigate
the problem.
