Reverse DNS (PTR) Problems Exist

The system uses an alternate HELO of nc-ph-3467.servereg.com when sending mail from the servereg.com domain.

The system sends servereg.coms outgoing email from the 66.29.138.11 IP address. The only PTR value for this IP address must be nc-ph-3467.servereg.com. This is the name that this server sends with SMTPs HELO command to send servereg.coms outgoing email.
1 unexpected PTR value exists for this IP address:

  • server.servereg.com

To fix this problem, contact your system administrator and request that they replace all PTR records for 11.138.29.66.in-addr.arpa with the following record at ptrdns1.registrar-servers.com and ptrdns2.registrar-servers.com:
