Plesk 8.6 / CentOS
I have a client that hosts their website on my Plesk server.
They have an in-house Exchange server which sends mail directly via DNS.
They have ATT for ISP.
I asked ATT to setup RDNS for their inhouse servername -> Local Office IP.
ATT wont setup RDNS but will transfer the DNS zone.
So I had them transfer it to my webserver nameserver.
I setup a PTR record under the clients domain account.  IPADDRESS > office.domain.com

When I run a report at dnsstuff it shows that ATT has given my server authority but when queried it doesn't reply with a PTR record.

I just moved this webserver so it got new IPs but that was a couple weeks ago and i highly doubt its DNS lag.  
This did work prior to upgrading the webserver.

12.144.217.82 / 8      PTR      office.arcoa.com.
is how its set in Plesk

How I am searching:
Asking g.root-servers.net for 82.217.144.12.in-addr.arpa PTR record:  
       g.root-servers.net says to go to dmtu.mt.ns.els-gms.att.net. (zone: 12.in-addr.arpa.)
Asking dmtu.mt.ns.els-gms.att.net. for 82.217.144.12.in-addr.arpa PTR record:  Got CNAME referral to 82.80/28.217.144.12.in-addr.arpa. at server ns1.solonameserver.com. (zone 80/28.217.144.12.in-addr.arpa.) [from 12.127.16.70]
Asking d.root-servers.net for 82.80/28.217.144.12.in-addr.arpa. PTR record:  
       d.root-servers.net [128.8.10.90] says to go to CBRU.BR.NS.ELS-GMS.ATT.NET. (zone: 12.in-addr.arpa.)
Asking CBRU.BR.NS.ELS-GMS.ATT.NET. for 82.80/28.217.144.12.in-addr.arpa. PTR record:  
       cbru.br.ns.els-gms.att.net [199.191.128.105] says to go to ns2.solonameserver.com. (zone: 80/28.217.144.12.in-addr.arpa.)
Asking ns2.solonameserver.com. for 82.80/28.217.144.12.in-addr.arpa. PTR record:  Reports that no PTR records exist [from 208.64.64.90].

Answer:
No PTR records exist for 12.144.217.82. [Neg TTL=10800 seconds]

Details:
ns2.solonameserver.com. (an authoritative nameserver for 12.in-addr.arpa., which is in charge of the reverse DNS for 12.144.217.82)
says that there are no PTR records for 12.144.217.82.

The PTR record is setup by whoever owns or administers the IP block (range), not by the person that manages the DNS zone. However *sometimes* this is the same person or company.

"I asked ATT to setup RDNS for their inhouse servername -> Local Office IP.
ATT wont setup RDNS but will transfer the DNS zone."

anyway I found its not possible in Plesk without breaking some other things so I just routed their mail through a smarthost.
