PTR Records

[Nomis]

Hi

I have completed a installation of ispCP R1 on a server and have created a domain however when I try and register the domain the registrar tells me they can not complete the registration because the Reverse lookup or PTR records are not there or do not point to the correct IP.

Sorry new to all of this so it's greek to me.

Can any one help me. From the research I have done, it has to go in the named.conf file but but have no idea how to set it up. And I presume that any and all domains created will require PTR records. I see the zone files get generated automatically once you add a new domain. Is there a way to do this with the PTR records too..

Regards
