He runs his own (Merek) email server and does his own forward DNS and we do the RDNS since he uses our IPs.
We have no other customers complaining and I have sent test messages to AOL customers without any problem.
Can anyone point me in the right direction to get this resolved (no pun intended). Here is a copy of the customers report
and there is a log excerpt attached..
Thanks,
Gary
It appears that it is a reverse dns problem. I have attached log files from my mail server. Once the server is connected to aol's mail server, aol's mail server responds back that there is no reverse dns. Please let me know what pbi says. I have clients breathing down my neck about not being able to send email to aol.

Hi Paul,
Here's what I get: Asking h.root-servers.net for 225.194.212.207.in-addr.arpa PTR record: h.root-servers.net says to go to figwort.arin.net. (zone: 207.in-addr.arpa.) Asking figwort.arin.net. for 225.194.212.207.in-addr.arpa PTR record: figwort.arin.net [192.42.93.32] says to go to ns1.pbi.net. (zone: 212.207.in-addr.arpa.) Asking ns1.pbi.net. for 225.194.212.207.in-addr.arpa PTR record: ns1.pbi.net [206.13.28.11] says to go to ns1.comsec.net. (zone: 194.212.207.in-addr.arpa.) Asking ns1.comsec.net. for 225.194.212.207.in-addr.arpa PTR record: Reports mail.tommydew.com. [from 207.212.96.4]
Answer: 207.212.194.225 PTR record: mail.tommydew.com. [TTL 86400s] [A=207.212.194.225]
>>>This is correct<<<
However on a DNS traversal I get:
Results from ns1.comsec.net do not match results from ns1.pbi.net. Results from ns1.comsec.net do not match results from ns2.pbi.net.
There should be no RDNS records on the pbi.net DNS machines since ns1.comsec.net & livewire.comsec.net have been delegated authority for my subnets. I have checked resolution using several outside DNS servers and it has resolved your email server correctly. If you have a copy of the AOL rejection message please forward it to me. I will contact PBI to follow up.
Thanks,
Gary

Gary,
On one of my mail servers, I am getting rejected email from aol because of no reverse dns (ptr record). And it appears that you have livewire.comsec.net, ns1.comsec.net, ns1.pbi.net and ns2.pbi.net listed as dns servers for 207.212.194 class c. comsec.net servers respond correctly for the ip. But the dns servers on pbi's side respond incorrectly. I do not know if the replication between your servers and pbi have stopped, but please let me know what you find as I need to resolve this issue. Attached below is a report of the mismatching info. Please let me know the status of this info.
