Uhhh... remember that the "From:" line may not ALWAYS be the person
posting the message, if there is a "Sender:" line. (See RFC822 for an
example in which a secretary sends boss's mail.) ((And aren't there
"Resent-...:" headers, too?))

Anyway, the 'uid' (if not "uucp") should match ONE of the valid sender
lines, but not necessarily "From:".
