AT&T customers have contacted us saying they can't reach any of our DNSBLs, seems AT&T have defined a fake sbl.spamhaus.org zone in their DNS servers so when AT&T customers ask AT&T's NS 12.149.189.2 for sbl.spamhaus.org they get: ...
I was looking at this some more last night, and noticed this appears to have been some kind of mistaken identity issue. Check the whois and PTR for 12.149.189.2. It certainly doesn't appear to be an AT&T maintained DNS server.
No mistake, although 12.149.189.2 is a customer's NS it uses AT&T's NS as the resolver. We've have complaints from other AT&T users about the same thing, as does another DNSBL (SpamCop), and there's now an answer from AT&T to one of their customers who forwarded AT&Ts response:
"I finally talked to someone who knows what the problem is. Your sbl sites have been blocked by the standard DNS forwarders supplied by ATT. This is due to the workload being generated on them from mailservers."
