The sender you are trying is not a local address, and everything
nonlocal is passed on to the smarthost.

Exim does do sender verification by going through the motions of
sending a message to the sender without actually sending a message.
Since a message to the non-local sender will be sent to the smarthost,
the local exim considers the sender address as verified.

Ok. The issue we have here is specific to smarthost setups.
