From one newb to another... in addtion to mailing the message, I would
unset a couple of (all?) your $_POST values. Then add some code prior
to mailing to make sure they have values. Hitting submit once would
send the message. Hitting submit a second time would throw up your
error message about missing values (because you just wiped them out.)
