                        Mail Retrieval via FTP

  We propose two new FTP commands called ReaDMailFile and ReaDMail.
  These commands are intended to be symmetric with respect to the
  current MLFL and MAIL commands.  They would allow a user to read his
  mail at one or more sites without incurring the overhead of logging
  in and without having to use several different retrieval methods.
  The user might go further and create a program to go around to all
  the server sites and retrieve his mail for him.  The current FTP
  mechanisms provide for password protection, should security be
  required.

  This proposal brings into focus, once again, the problems of
  different users with the same ID, and to a lesser extent, one user
  with multiple IDs.  This RFC does not attempt to address these issues
  at this time, as much effort is currently being devoted to them.
  However, we believe that a satisfactory system for network mail
  should include a mechanism to enable each user to have mail for him
  sent to a single repository (ideally, the site of his choice).  We
  further believe that the two commands proposed here would be useful
  in such an environment as well as within the current network
  environment.

  The format of the commands is

  COMMAND    REPLY
             success        fail

  RDMF       200,250,330    433,450,451,454,455,457,500,507
             secondary replies:
             252            452

  RDML       152,330        433,450,451,455,500,507

  The success reply 200 would take the text "NO MAIL NOW".  For the
  RDMF command the mail itself is transferred over the data connection,
  and the FTP replies come over the TELNET connection.

RFC 458                  Mail Retrieval via FTP         20 February 1973


  For the RDML command both the mail and the FTP replies come over the
  TELNET connection.  The reply 152 is a new code meaning "mail text
  follows" the text that follows may be "NO MAIL NOW".
