I think another issue to keep in mind is that certain broken e-mail clients
also send messages with the empty envelope sender in response to spam. "I'm
on vacation", "This message has been read", "This message has been deleted".

Maybe the "smarthost" is for end-user e-mail clients, and not for servers,
and therefore has stricter rules in order to avoid these issues?
