Re: Reverse DNS or PTR Help!!!

Jeff,
The reverse DNS has to be managed by the people who assigned you the IP address, normally the ISP. They control that range of IP's, and so by setting up a reverse record for your domain they are confirming that you have a right to use that IP address. By definition no-one else can set up the authoritative reverse zone. Anyone else (like your website hosting company) can try, but since they are not authoritative for the IP addresses, no-one will ask them.
If your ISP won't do it, you could as you suggest forward to a smarthost

Our ISP, Embarq will NOT create custom PTR records. We have their DSL service
and recently implemented a SBS with Exchange.

Our website hosting company is managing our DNS and says they created a
reverse lookup for our mail server, but a NSLOOKUP shows it is not working.
Doing a lookup on our ip address resolves to the hostname of our router.

It was suggested to setup a SMARTHOST.

So the question is, although our ISP does not support custom PTR records,
should our website hosting company that is managing our DNS be able to create
a working PTR, or do we really need to setup a SMARTHOST?

Since the reverse DNS is not working, many of our emails are being returned
and mistaken as spam.
