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.
