A properly designed system would have IMHO added you to the whitelist

not a spammer because he sent you a message) then you should be
automatically whitelisted.
Careful, this is fragile. My envelope frequently doesn't match my
From:, and in the case of role addresses, the initial To: won't match my
From: or envelope.
Some of the difficulties to the challenge / response system is that it
is not standardized and currently requires a separate e-mail from you
with something that identifies you as a person rather than a machine.
I believe that it would be much easier if there were a standard for
this sort of thing and then the challenge / response could be built
directly into the e-mail client.
Modulo turing tests, and even there where the Turin test form becomes
standardised...and into spammer software that manage to run an MX for a
while.
