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IANA, is hereby obsoleted and should be withdrawn.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?
