On thing to watch... if sender_verify is used (or sender_try_verify), then
*local* addresses that don't work get rejected. For example I put
together some code on a box yesterday which was sending out messages from
smsgate@???.
Our central mail system, which handles theplanet.net, had no alias or user
for smsgate, and so the box was unable to send messages to local users!
