Yes, I think that's right.

Out of curiosity, what kind of list does that, and why?

To the first part of your question I would have thought that the
response does not depend from the list but that the problem happens
everytime someboy Bccs a list?

Well, such a message would lack the To:the-list header. But I'd expect the List-ID: et al to be present, having passed through the list software.

But if eg it went to you personally (directly) and also via a list, you will get 2 copies: one with list headers via the list and one without (the direct copy to you). You'd need to examine the not-recognised message headers to see which, and why.

This discussion is a little moot without seeing example message headers - the possible behaviour is quite varied.
