The MHS-DS Working Group works on issues relating to Message Handling
Services use of Directory Services. The message handling services are
primarily X.400, but issues relating to RFC 822 use of Directory and
Directory support for RFC 822 and X.400 interworking are in the scope of
the group. Directory and Directory Services refer to the services
based upon the CCITT X.500 recommendations and additional ISO
standards, stable implementation agreements, and RFCs, as specified by
the OSI-DS Working Group. The major aims of the MHS-DS Working Group

  1. Define a set of specifications to enable effective, large-scale
    deployment of X.400.

  2. Study issues associated with supporting X.400 communities which lack
    access to X.500 Directory, and define requirements for tools which: (a)
    extract information from the X.500 Directory for use by non-X.500
    applications, and (b) upload information into the X.500 Directory.

  3. Coordinate a pilot project which deploys MHS information into the
    X.500 Directory and uses it to facilitate mail routing and address
    mapping. The results of this pilot will be documented, and experience
    gained from the project will be fed back into the Internet
    specifications created by the working group.
