According to DNSREPORT.COM PASS Reverse DNS entries for MX records OK. All of your mail server(s) have reverse DNS (PTR) entries. RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. The reverse DNS entries are:
