Sébastien, I'm sorry, I gave a bad answer back then, because I 
misunderstood Mutt's mailing list code. I think I understand it now.

Mutt detects that a message came from a list by comparing addresses in 
the message's To: and CC: to addresses predefined by command 
"subscribe" or $auto_subscribe. That doesn't work if the list address 
does not appear in To: or CC:, which apparently is your situation. I 
think that's the problem.

I think Mutt should (also) look at List-ID:, which would work here, but 
currently it doesn't.
