I am not sure if that is a healthy direction to go.

If a local outbound relay is written with the knowledge that it will
never be talking to the SMTP at the final mailbox directly, I would
expect that it may not implement any validation at all, relying on
the "next hop" smarthost to reject anything invalid it throws at it.
