Abuse addresses at att.net

[Martin]

It seems that forwarding a SPAM originating from AT&T's network
promptly gets your server blocked. This applies to both "abuse" and
"postmaster" at att.net.

You get something like:
> 521-ip.ip.ip.ip blocked by sbc:blacklist.mailrelay.att.net.
> 521 DNSRBL: Blocked for abuse. See http://att.net/blocks

I haven't found anyone who has worked out the rationale for being on
blacklist.mailrelay.att,net. They may just be using a random number
source to feed their block list.

Of course the spammer don't complain (well don't complain as often),
so it might be a brilliantly effective list, with just a small false
positive rate, but I'm not betting any money on it.

I'd ignore it, no one ever complained, so I'm guessing their users are
resigned to not getting email.
