How to configure reverse DNS on your dedicated server

Introduction

reverse DNS (also known as rDNS) allows you to link an IP address to a subdomain. This is the opposite of regular (forward) DNS where you can link a domain to an IP address. reverse DNS is one of the ways email servers use to verify that the sending server is not a malicious spammer. You can see it as an extra layer of security to your e-mail. If there is no valid rDNS setting, most email servers will reject the emails or mark it as spam. If the sending email server doesn’t have a reverse DNS record at all, that’s usually a sign of spam, and the email sent from such server is rejected by most email servers.
