Yes but as I wrote already, an anti-spam system that uses responses
can not do this because as I said the spammer could mimick a list to
escape the anti-spam response mechanism.
Thus the only answer is for lists to declare a null address they want
auto-responses sent to. If they did that, then you wouldn't need
complicate heuristics and you wouldn't see posts like this on this

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.
