The MHS directory user package contains definitions to support the use of the directory in accordance with the standard X.400 (1988) User Agents and Message Transfer Agents (MTAs) for name resolution, distribution list expansion, and capability assessment. The definitions are based on the attribute types and syntaxes specified in X.402, Annex A. The definitions of the OM classes and OM attributes required to support these MHS attribute types are also included with this package. MHS Directory User Package describes the MHS directory user package in detail.
