Restrictions on the Content-Type "message"

1999-01-03 05:05:29
Below is a quote from DRAFT Mime headers 0.4
by Charles Lindsey <chl(_at_)clw(_dot_)cs(_dot_)man(_dot_)ac(_dot_)uk>, which
is being developed by the USEFOR IETF group:

    6.x.5.3 Message/news obsoleted

        The Content-Type "message/news", as previously registered with
        IANA, is hereby obsoleted and should be withdrawn. The reason
        is that, according to RFC-2045, it is expressly forbidden for
        any "message" type to use a transfer-encoding other than
        "7bit", "8bit" or "binary", thus preventing a news article
        which makes full use of UTF-8 characters in its headers, or
        which uses (as it SHOULD) "8bit" as its own transfer-encoding,
        from being passed through a 7bit transport medium (recall that
        it is not permitted by this document for the transfer-encoding
        of a news article to be changed).

How does this conclusion influence e-mail standards?
