How to check a Reverse DNS / PTR record on a domain
1) Find the host name of their mail server
nslookup
set type=mx
company.com
Let's say in this test the result is mail.company.com
2) Ping mail.company.com and get the IP
3 Do a PTR lookup on the IP
nslookup
set type=ptr
IP ADDRESS HERE
It should resolve back to mail.company.com
