We've got an A Record for our mail server and an associated MX record. We are moving to a new location and will have a new IP address. ATT hosts our DNS and they won't let me create an MX record that is associated with an IP address. it has to be associated with an A Record.
My question is: can we have two A Records for one email server - mail.our_domain.com?
I can ping the new IP address at the new modem at the new location, but there is no server set up there.
Will we lose email with two A Records when there is only one server connected to one of those IPs?
