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.
