2011-12-27 I answer an e-mail from someone with an ...
I answer an e-mail from someone with an @bellsouth.net address, and I get the error message:
<<< 550-aa.bb.cc.dd blocked by ldap:ou=rblmx,dc=att,dc=net
<<< 550 Error - Blocked for abuse. See http://att.net/blocks
554 5.0.0 Service unavailable
But http://att.net/blocks is useless in finding out why att.net would think my IPv4 address is a spam source. The available options seem to be I am the responsible admin for this system and I did (x and y) to stop the well-known spamflood or I am an end-user and I will wait nicely for the admins to sort this out.

The second option does give an e-mail message after a while which is not very informational:
We are writing to let you know that we are blocking messages addressed to one of our customers at the domain bellsouth.net by one of your customers at domain kzdoos.xs4all.nl. The stream of messages coming from your system appears to consist mostly of unwanted commercial e-mail (UCE, or "spam"). To protect our system a nd to ensure that it operates well for all of our customers, we have decided to block all messages originating from your system.

Please consult your logs to see what might be causing this situation and how it can be fixed. Then visit http://rbl.att.net/block_inquiry.html to request a remo val of the block. Most requests for removal are honored within two days.

The specific error message received by your customer was: 550-aa.bb.cc.dd blocked by ldap:ou=rblmx,dc=att,dc=net

Thank you for your assistance in helping our respective customers communicate.
All I see in the logs with att.net / bellsouth.net is incoming spam.

So I will request a delisting with as reason 'no OUTGOING spam found in the logs'.
