I disagree. The 'correct' answer is that if you use an auto-response
(or other challenge) system then you *MUST* whitelist the mailing
lists to which you subscribe.
Oh I agree with that and had already written that much earlier:

"If I whitelist the people on the list, they never see my auto-response..."
I think you miss the subtle difference here. I did not suggest
whitelisting the people on the list, but the list *itself*. That is,
you should not sent challenges to mails sent via the mailing lists to
which you subscribe. Thus if I post to a list to which you also
subscribe, I would not expect to receive an auto-response. But if I
was to send you email directly, not via a mailing list, I would expect
to receive an auto-response from you.
