Ironport Question reg custom domains

I'm hoping someone can help me understand the capabilities or limitations of Ironport. I work in an environment where another department owns and operates the mail relay operations, so I have no access to the device or support to advise or dispute what they are saying.

Situation: We have a closed application environment which uses a custom defined domain (foo.bar, host1.foo.bar, host2.foo.bar, exporter.foo.bar)  We have a system that sends email out to the real world (exporter.foo.bar) and its outgoing relay is the ironport appliance.  The problem is, when a remote mail site is down or bounces the email, the ironport does not know where to send the bounce message because it doesn't know how to send to exporter.foo.bar.

Problem: the admins for this ironport appliance report that it is impossible to configure it to send to exporter.foo.bar because "bar" isn't a "valid" domain (eg: .com, .net, .edu, etc...)  

Can someone confirm if this is true or not? Is the Ironport so tightly integrated with LDAP, or AD, or some flavor of Mickysoft DNS that you can't simply add a mailertable type entry to send email destined for "foo.bar" to a particular IP address?

Not true.

Under Network>SMTP Routes there needs to be an entry for example.foo.bar to direct mail traffic to a mailhost for that domain.

There may be other things that they haven't configed or have misconfiged that need looking at..
