Hi,

What i am suspecting is the misconfiguration in DNS server , As the reverse DNS entry for 10.120.0.117 would have configured as wcrbdepjozrc054.crb.apmoller.net .

As the defination for says Reverse DNS (rDNS) is a method of resolving ip address into a domain name, just as the domain name system DNS resolves domain names into associated IP addresses.

I would suggest just check out with DNS administrator and explain him about the above happening.

Hope that help
