I was checking all of my settings using DNSstuff.com and came upon this
error. Can anyone tell me what this means and how to correct it? Also, why
does it say "customer-reverse-entry"? Thanks for any advice you can provide!

xx.xxx.xx.xx PTR record: customer-reverse-entry.xx.xxx.xx.xx. [TTL 3600s]
[A=None] *ERROR* A record does not point back to original IP.

TIA - Rob

This is when the PTR record points to a name that points to another IP
address.
Example:
1.1.168.192.in-addr.arpa. "PTR" points to server.example.com but,
server.example.com "A" (Address) record points to 192.168.1.2
 
Thanks Kevin. So all I need to do is create a PTR record pointing back to a
host name with the correct IP of the nameserver?

Regards,

Rob

If the reverse is a PTR for the nameserver IP then, you are correct.
In truth whatever name the PTR points to, that name must resolve to the IP
of the PTR.
