Here is the scenario:
mail.domain.com is hosted to IP 1.2.3.4 inbound at serverX(which is a SPAM filter front end), outbound mail comes from serverY(actual mail server) at IP 5.6.7.8 for same domain. Incoming has no issues since MX and RDNS reflect IP 1.2.3.4, but outbound has some issues when the server receiving the e-mail at anothermail.anotherdomain.com checks the IP and sees RDNS at IP 1.2.3.4 coming from server IP 5.6.7.8.
My options include:
1)pointing outbound mail via smart host to 1.2.3.4 and all would be good, but am having issues getting that to work.
or
2)Changing name of server at 5.6.7.8 to mail2.domain.com and creating another RDNS for it. Not sure if MX is required for outbound or if anything else also needs to be done.

I would do #2, but figure out what's going on with #1.

For #2 you dont need an additional MX record, just reverse DNS.

Once you got #2 working, should something ever happen to that server or connection, just shoot email out #1 as a back up solution.
