It doesn't really have anything to do with your mx records, outgoing mail and incoming mail can be routed through separate servers.

PTR should always match the hostname of the server. So if you have two outbound servers mail1.example.com and mail2.example.com then correct PTRs would be

mail1.example.com for the IP of mail1.example.com
mail2.example.com for the IP of mail2.example.com

Should be like : IN PTR mail1.domain.com. ( on first domain zone ) IN PTR mail2.domain.com. ( on secound domain zone )
