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
IP-IP-IP-IP.HOST.DOMAIN.TLD ? ???
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?
