Reverse DNS Match Mail Server Banner for 2 names?

Hi
I have 2 internet lines physically from different providers. Just in case one is out it can go to the other.

I want to have 2 mx records.
5 mail.myco.com
10 mail2.myco.com

My sonicwall spam filter gets all the email from my exchange on outgoing. There is a section in there where you can type stuff into the banner. Right now it just says mail.myco.com should i also add mail2.myco.com for when my email is checked for a valid reverse dns name?

Thanks.

The PTR check is for outbound email, not inbound. Does your Exchange server deliver email to the sonicwall device or direct? In these cases it is often better to have email delivered to a central server elsewhere so that you aren't dependant on which connection it is and all of the DNS settings matching.
