Backup mail servers are associated with the name that the MX record is
attached to, not the servers that are listed. I.e. when you have
foo.com. MX 10 server1a
MX 10 server1b
MX 20 server2a
MX 20 server2b
it affects mail addressed to user at foo.com. The sender will first try to
send to each of the MX10 hosts in a random order, and then try to send to
each of the MX20 hosts in a random order.
