Reverse DNS - how to correctly configure for SMTP delivery

I ran a DNS check and ended up with the following error:

FAIL: Found reverse DNS entries which don't resolves
All IP's reverse DNS entries should resolve back to IP address (MX record's name -> IP -> IP Reverse -> IP). Many mail servers are configured to reject e-mails from IPs with inconsistent reverse DNS configuration.

How do I properly configure and it so it goes to an IP?

Contact the provider who assigned the IP address to you. Unless they have delegated reverse DNS to you, then they will have to set it for you.
