The way I understand, transport map selects messages based on
recipient's address or domain. In the above example, only messages
destined for example.com would get routed through the right interface.
Once messages end up in the queue, qmgr uses trivial-rewrite to
resolve recipient's address and selects a transport based on that. Or
am I wrong?

I need to route messages based on either sender's address/domain (this
would suffice) or incoming interface (better).

Thanks for the suggestion anyway!
