No mistake, although 220.127.116.11 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:Steve Linford wrote: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 18.104.22.168 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 22.214.171.124. It certainly doesn't appear to be an AT&T maintained DNS server.
"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."
