2.3.  Relation To Email and MIME

   The primary intent of this standard is to describe the news article
   format.  Insofar as news articles are a subset of the email message
   format augmented by some new headers, this standard incorporates many
   (though not all) of the provisions of [RFC 2822], with the aim of
   enabling news articles to pass through email systems and vice versa,
   provided only that they contain the minimum headers required for the
   mode of transport being used. Unfortunately, the match is not
   perfect, but it is the intention of this standard that gateways
   between Email and Netnews should be able to operate with the minimum
   of tinkering.

   Likewise, this standard incorporates many (though not all) of the
   provisions of the MIME standards [RFC 2045] et seq which, though
   designed with Email in mind, are mostly applicable to Netnews.
