Configure reverse DNS to match SMTP banner and Forward DNS
Posted on 2013-06-25
In an effort to mitigate the residual effects of our recent virus outbreak, I am now finding out our IP rating is poor and through a few searches, I have found out others in my poisition have been able to increase the rating by resolving reverse DNS issues.
I ran a few SMTP diagnostics on our public IP and this is the results I have received;
Reverse DNS (PTR) exists and claimes to be: mail.imgps.com
Forward DNS for mail.imgps.com is: 220.127.116.11
WARNING: Forward-DNS does NOT match Reverse-DNS.
DNS is INCONSISTENT.
Please request your Admin or Provider to fix this.
What do I need to do in order to resolve this issue?
Where can I find out my current SMTP domain in order to match this with what is being published?
