I never proposed breaking 2046.  It only gives an example, it does not
dictate what must be done.  If you have no text/plain parts to include, you
don't have to do anything like what 2046 outlines.

2046 is great.  The example given in 2046 is not so great, IMHO, because
it's needlessly complex.  There's no point in _asking_ for MUAs to screw
things up.

All problems resulting from messages I generate are indeed my problem, at
least from a user's standpoint.  Whether I choose to do something about
them is another matter; I will make accommodations for stupid MUAs only as
far as it doesn't harm things for good MTAs.  If possible, I think it smart
to at least make the effort to avoid breaking things when you can.

But if I put Date:, From:, To: and a blank line at the top of the index, it
becomes a legal message/rfc822 and can be placed in the digest without
violating RFC2046.

That would be a violation of RFC2046, and I have no intention of doing it.

Well, that's a more difficult subject.  Probably as difficult as moving
Mt. Everest, or BillG's pile of cash (whichever is heaver; I suspect the
