The broken PGP signature speaks the message from the mailing list NOT 
being the message that you sent.

It seems to me like there are two schools of thought; 1st the message is 
the body and all headers / envelope that you send (this is where I land) 
and 2) the message is /only/ the body and maybe only in spirit.

My opinion is that mailing lists are a terminal point.  As such they are 
an MUA, not an MTA.  Mailing lists receive a copy of a message and 
generate a new and completely independent message substantively based on 
the message they received.  But the message in to and out of a mailing 
list are two substantively different messages.  As such, I believe they 
should have different Message-IDs.

I think this view on mailing lists also speaks to all forwarding issues 
that I'm aware of.  Any shortcuts that fall short of this end up having 
problems.

But that's my opinion and I digress.
