Re: the authors of RFC 2317 have a question for at&t worldnet
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.
