Setting Up Reverse DNS

[Guest]

Hello Everyone and thanks for your help in advance. I am running and
Exchange 2003 Server within my network. I am having difficulties with some
email addresses as they are requiring reverse DNS records. However, I am
unclear as to how exactly to do this. I have two DNS servers on the network,
but am not sure how to properly configure the PTR. Any help is greatly
appreciated. Thanks.

Unless your ISP has delegated the reverse lookup to your DNS servers, it
won't do you any good to create a reverse lookup or PTR for your public IP
address.
You will need to contact your ISP about creating the PTR records for your IP
or delegating the reverse lookup to your DNS server.

Thanks Kevin. Is this becoming a typical situation for mail hosting?
