Received >>> 554 imta13.emeryville.ca.mail.comcast.net comcast xxx.xxx.xxx.xxx comcast requires that all mail servers must have a ptr record with a valid reverse dns entry. currently your mail server does not fill that requirement. for more information, refer to: http://www.comcast.net/help/faq/index.jsp?faq=securitymail_policy18784
When I ping the ip with a -a, it resolves a name. The name is also listed in our DNS MX records. It's listed as the priority record but it is listed.
Is a PTR record different? Not sure what I need to do next.
