IESG Note

   The protocol specified in this document may be satisfactory for
   limited use in private wireless IP networks.  However, it is
   unsuitable for general-purpose message transfer or for transfer of
   messages over the public Internet, because of limitations that
   include the following:

   - Lack of congestion control

      EMSD is layered on ESRO [RFC 2188], which does not provide
      congestion control.  This makes EMSD completely unsuitable for
      end-to-end use across the public Internet.  EMSD should be
      considered for use in a wireless network only if all EMSD email
      exchanged between the wireless network and the public Internet
      will transit an EMSDSMTP gateway between the two regions.

   - Inadequate security

      The document specifies only clear-text passwords for
      authentication.  EMSD should be used across a wireless network
      only if sufficiently strong encryption is in use to protect the
      clear-text password.

   - Lack of character set internationalization

      EMSD has no provision for representation of characters outside of
      the ASCII repertoire or for language tags.
