I have a location with 2 lines, from 2 ISPs, a T1 and a Comcast line.
Each is "business" with static IP.
The T1 ISP has the DNS records for the domain.
So let's say is has mail.company.com
But I want a mail2.company.com to be found via the comcast line.
And an mx record as well.
Does that means I can no longer use the DNS server at the "primary" ISP for this, since a reverse lookup won't work for the 2nd line, or is there some type of entry I put in somewhere to allow it to happen?
