On your DNS server, create two MX records, one for serverA.company.com and
one for serverB.company.com, and point both of them either to the IP
address of the server, or an A record in the same database that is defined
with the IP address of your server. Next, configure the Routing tab of
your IMS connection to define both serverA.company.com and
serverB.company.com as inbound domains.
