What is the MHS MD Registration Service?
The Message Handling System (MHS) Management Domain (MD) registration service provides the registrant with a management domain name which can be used to identify an Administration Management Domain (ADMD) in the U.S. or a Private Management Domain (PRMD) under ADMD in the U.S.
An ADMD is a management domain which offers CCITT X.400 and ISO/IEC 10021 messaging service to the public. A US ADMD voluntarily upholds the behavior characteristics defined for ADMDs in the "Behavior Guidelines for Voluntary Participation within the US National X.400 MTS" and agrees to the Memo of Understanding written by the US National Message Transfer Service Implementors' Group.
A PRMD is a message handling system management domain that is managed by a private organization.
ANSI maintains a data base that is searched with every new registration request to ensure that duplicate identifiers are never registered.
Registration guidelines have been developed to administer the MHS MD registration process. The procedure specifies the syntax of names assigned by the MHS MD Registration Authority. The guidelines are available from the Registration Coordinator Henry Cheung (Phone: 212.642.4975, e-mail: ISOT@ansi.org).
In order to recover costs, ANSI charges a one-time registration fee for this service.
