Re: reverse ptr question

Hi johnpsr1.  The rDNS/PTR records should match your mail server name.  The failure message will contain your sending server name as well as the PTR data entry.  If you will send me a private message with the complete failure message or bounce back message and I can make the necessary corrections.

 

Thank You
