One more thing to add. Is there any tools that will tell you what dns server is responding when you do a reverse dns lookup? Basically my ISP is saying that because I run my own dns, my server has the problem, when I asked them to add my reverse domain lookup.
Who is your ISP? To be perfectly blunt, whichever tech support rep you spoke with has no idea what he/she is talking about. You ALWAYS want reverse DNS (PTR) records to reside on the name servers of the company who owns the IP block. Do a "whois" lookup to find out who is authoritative at DNSStuff.com
. Another option is to have them do a classless delegation of the range they route to you, but they still have to add that on their end. This is all assuming that you have a static public IP range being routed to you.
Hope this helps.
