How do we correctly get a rDNS / PTR record entered associated with the mail host IP address in order to send to AOL addresses?  And who's job is it to complete this?

Background:
We host our own mail on MS Exchange .
MX record points to exchange Server IP Address.  
The ISP issued Static IP address (of teh Exchange server) is different than web host of the domain.

Reverse DNS (via DNSStuff) shows error and reports back WebHost IP address rather than the Exchange Server IP address so we assume not correct here.
ISP says WEB Host has job of creating correct rDNS / PTR record according to DNS RFC (Request for comments).....Web host does have ability to create other custom DNS records such as A records, MX, CName etc...(but no available PTR choice).
Web Host says ISP is responsible for record change; ISP says Web host (DNS controller) is repsonsible per RFC...

Questions are:
Who is responsible and how to get it done in our setup described above?  Basically, how can we correct this setup so that our Excahnge server has correct rDNS and is able to send mail to AOL addresses?  Are RDNS and PTR synonymous? Thanks in Advance!!!
