Reverse DNS checking from Exchange 2007

My Exchange 2007 is sitting in behind firewall and using NAT to map the public ip to local ip, one of my email recipient in internet who use reverse DNS lookup to check us but it said it is not matched.  I have PTR set in my DNS server already.

Is it possible to check how another party to look up my reverse dns record, if they check my mx record or just check my domain.

Because I am using MX Logic as a mail gateway to filter all spammed email, therefore all inbound email sent to MX Logic first then resent back to my Exchange server.  I am not sure, should I use my own domain and my ip for PTR record or using MX Logic.  Please help me to the correct PTR.
