Doh! I realized what I was asking a few minutes later, forgetting all the
one-way MTA's in the world.

In an ideal world, an ISP's submission server should note the IP that submits
email and note the matching account in the queue. If the delivery is then
rejected, it has a reasonable place to send the bounce to.

Following this idea, how might one set up MD on an office gateway server to
NOT let locally-generated (on the same host) bounces escape the premises, but
pass bounces from other internal servers?
