Positive it's not happening. People sending from legit addresses don't get
a bounced message saying the message could not be delivered to xyz user on
my system. It just delivers to the postmaster account and the person that
wrote the message hasn't a clue that it wasn't delivered.
Also, how can I turn off the feature to have the message be sent to the
postmaster account as well. I'd like it to be bounced and deleted.
