I thought the difference between message/rfc822 and message/http
was that the outermost heading, the header immediately following
the Content-Type:Message heading, was to be formatted and
interpreted according to e-mail versus http rules. For example,
a message/http header can contain an "Age:" header field, but
such a field is undefined in a message/rfc822 heading.

However, it is probably not permitted to include Content-Encoding
or Transfer-Encoding in headings transported through e-mail,
even if the heading is of type message/http, since those encoding
format may not be permitted in e-mail?
