Hi all!

I have been approached with the following questions which I do not know
how to answer

Q1: A server with 2 NIC's, each NIC with an IP from 2 different ISP
(redundancy).  NIC number 1 has a MX record with a lower values and NIC
number 2 has a higher value.  In theory, if the internet connection to
NIC 1 fails, email servers will use the MX record with the higher value.
However, when creating the domain I can only pick 1 IP?  Is this doable?

Q2: Same as above with 2 domains with each one having its own IP
address.  NIC 1 with 2 IP's from one ISP and NIC 2 with 2 IP's from
another ISP.

Can this be done?  

Thanks...
