Addresses can be easily faked or spoofed.  Even passwords can be guessed.  Only
the challenge and response method that LISTSERV's OK-confirm mechanism uses is
reasonably secure and even it is vulnerable to a wire-tap (have fun tapping an
OC-3 line...) or physical compromise of the sender's machine by unauthorized
persons.
