	Mailman is already doing MIME bodypart stripping, based on 
content-type values, etc....  It doesn't take much of a stretch of 
the imagination to take that same type of mechanism and apply it to 
the RFC2822 headers as well.

	Okay, add Message-ID to the list of standard headers that would 
typically be kept.

	Is it such an extraordinary step?  IMO, that's the real point 
under discussion.

	There are so many clueless users out there that insist that you 
protect them from their own stupidity, and they seem to go out of 
their way to use products from certain companies (who shall remain 
nameless) which likewise seem to go out of their way to do extremely 
stupid and dangerous things based on input from sources that are not 
proven to be trustworthy.

	This is part of the slippery slope I was talking about.  At what 
point do you stop trying to fight the billions of lemmings that are 
running you over on a moment-by-moment basis, and you start trying to 
do something to protect yourself, your systems, and your users, 
against them?

	In a sense, this is also what spam and spam fighting is all 
about.  More and more people are insisting on senders that must meet 
ever more stringent requirements, before the connection or message 
will be accepted.
