Yes, that's right. I think this is the point that you may have
overlooked, Robert. The routers are used at SMTP ACL time when an
address is verified - so they can influence the status code at that
point. In fact, you might like to add verify_only to the above router,
so that it is *not* used when actually deliverying a message.
