Message Handling System and Management Domain Name Registration
Fact Sheet
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 Karen Hughes (Phone: 212.642.4992, e-mail:
khughes@ansi.org).
In order to recover costs, ANSI charges a one-time registration fee for this
service (See Fee Schedule).
How does an organization request registration?
An organization seeking registration of management domain names should contact
ANSI to obtain a Request for Registration application form. Upon request for an
ADMD or PRMD, ANSI will submit the MHS-MD name to a three-month public review
period in their bi-monthly publication Standards Action before the registration
is approved.
What is the syntax of a management domain name?
The name of a management domain must conform to the syntax below:

Does an organization have to register an MHS MD name in other countries?
An ADMD name registered by ANSI in the MD register is unique within the US and
if used with countryName=us in an Originator/Recipient (O/R) address, the O/R
address is globally unambiguous. If an originator wishes to operate an ADMD in
another country, for example Canada, it must register in Canada to use its name
with c=ca.
For PRMDs, if countryName=us and admdName =" ", the O/R address is globally
unambiguous. If the name is to be used with another country in the O/R address,
the name must be registered within that country.
How long will the MHS MD name be retained?
Forever. However, ownership of MHS-MD names may be transferred and they may be
suppressed at the request of the registered organization. There are also
provisions for changing registration information about the "owner" to
accommodate name and address changes as may occur.
What is the relationship between the ANSI Organization Name Register and
the MHS-MD Register?
The Organization Name Register and the MHS-MD Register are separate registers
in the U.S. An organization may wish to register in either or both registers
(with the same or different alpha-numeric names). Numeric names are only
provided by the Organization Name Register. An organization wishing to use an
alpha-numeric for an MHS-MD name needs to register this name in the MHS-MD
Register.
How do I submit the application and the application fee?
Completed applications should be sent to ANSI, at the following address:
Karen Hughes
Registration Coordinator
ANSI
25 West 43rd Street New York, NY 10036
Applications can also be faxed to the following: 1.212.398.0023.
The fee should accompany the application. ANSI accepts the following as payment: check, money order, American Express, Mastercard & Visa.
Note: Applications cannot be processed without the accompanying fee (see
fee schedule
). If the application is faxed and the organization wishes to pay by check the
Registration Coordinator will hold the application until such fee is received.
The same holds true for applications sent with a purchase order.
