I doubt that any mail client would include any old headers in reply e-mail,
as replies are newly created messages. The headers belong to the old
message; the new message has new headers appropriate for it. I'm pretty sure
that Outlook discards all headers, even on forwards.

Indeed, I'd never even realized that RFC-822 even defines reference headers
(they're so rarely used; the Ada-France messages do have them, but that's
the first time I've seen them in any mail - and I look at a lot of mail
headers). I doubt that it would make sense to copy those headers in e-mail,
unless the client knows what they are for (as in a newsreader). (How would
you know if they apply to the reply? How do you know what to add to them?
The contents of the reference header is not standardized for mail.)
