Last time I checked, that's a news header (the switch-protocol aspect
is part of why "Mail" is prefixed).  I don't exactly know why the IETF
has been unable to standardize this for mail, but there you have it.

Nothing wrong with asking for the feature of course (it's a good one),
but I would suggest retracting the words "broken" and "fix", and
saying "*pretty* please."
