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.
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?
