Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
In addition to developing International Standards, ISO/IEC JTC 1 also develops International Standardized
Profiles. An International Standardized Profile is an internationally agreed, harmonized document which
identifies a standard or group of standards, together with options and parameters, necessary to accomplish a
function or a set of functions. Draft International Standardized Profiles adopted by the joint technical
committee are circulated to national bodies for voting. Publication as an International Standardized Profile
requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC ISP 12062-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems.
This third edition cancels and replaces the second edition (ISO/IEC ISP 12062-3:1997), which has been
technically revised.
ISO/IEC ISP 12062 consists of the following parts, under the general title Information technology —
International Standardized Profiles AMH2n — Message Handling Systems — Interpersonal Messaging:
 Part 1: IPM MHS Service Support
 Part 2: AMH21 — IPM Content
 Part 3: AMH22 — IPM Requirements for Message Transfer (P1)

Introduction
This part of ISO/IEC ISP 12062 is defined within the context of Functional
Standardization, in accordance with the principles specified by ISO/IEC
TR 10000, “Framework and Taxonomy of International Standardized
Profiles”. The context of Functional Standardization is one part of the
overall field of Information Technology (IT) standardization activities,
covering base standards, profiles, and registration mechanisms. A profile
defines a combination of base standards that collectively perform a
specific well-defined IT function. Profiles standardize the use of options
and other variations in the base standards, and provide a basis for the
development of uniform, internationally recognized system tests.
One of the rôles for an ISP is to serve as the basis for the development
(by organizations other than ISO and IEC) of internationally recognized
tests. ISPs are produced not simply to ‘legitimize’ a particular choice of
base standards and options, but to promote real system interoperability.
The development and widespread acceptance of tests based on this and
other ISPs is crucial to the successful realization of this goal.
The text for this part of ISO/IEC ISP 12062 was originally developed in
close cooperation between the MHS Expert Groups of the three Regional
Workshops: the North American OSE Implementors’ Workshop (OIW),
the European Workshop for Open Systems (EWOS) (jointly with the
corresponding expert group of the European Telecommunications
Standards Institute - ETSI) and the OSI Asia-Oceania Workshop (AOW).
The first and second editions of this part of ISO/IEC ISP 12062 were
harmonized between these three Workshops and ratified by the plenary
assemblies of all three Workshops.
Responsibility for maintenance and further development of MHS ISPs has
been transferred to ISO/IEC JTC1/SC33/WG1, who have produced this
edition to encompass additions and corrections to ISO/IEC 10021.
Because new core requirements have been added for support of
Universal Characters in addresses which will take time to be implemented
within MHS systems, it is expected that the second edition of this part of
ISO/IEC ISP 12062 will remain available for an overlap period.

INTERNATIONAL STANDARDIZED PROFILE ISO/IEC ISP 12062-3:2003(E)

Information technology — International Standardized Profiles
AMH2n — Message Handling Systems — Interpersonal
Messaging —
Part 3:
AMH22 — IPM Requirements for Message Transfer (P1)
1 Scope
1.1 General
This part of ISO/IEC ISP 12062 covers message transfer between Message Transfer Agents (MTAs) in an
Interpersonal Messaging (IPM) environment using the P1 Message Transfer Protocol (see also figure 1). These
specifications form part of the Interpersonal Messaging application functions, as defined in the parts of ISO/IEC
ISP 12062, and are based on the Common Messaging content type-independent specifications in ISO/IEC ISP
10611.
1.2 Position within the taxonomy
This part of ISO/IEC ISP 12062 is the third part of a multipart ISP identified in ISO/IEC TR 10000-2 as “AMH2,
Message Handling Systems - Interpersonal Messaging”.
This part of ISO/IEC ISP 12062 specifies the following profile:
AMH22 - IPM Requirements for Message Transfer (P1)
The AMH22 profile may be combined with any T-Profiles (see ISO/IEC TR 10000) specifying the OSI
connection-mode Transport service.
1.3 Scenario
The model used is one of two or more MTAs intercommunicating within a Message Transfer System (MTS)
using the P1 protocol, as shown in figure 1.
P1
P1
MTA MTA MTA

Figure 1 - AMH22 scenario
NOTE - In an ITU-T context, a domain may be treated as an MTA for the purposes of conformance to the AMH22 profile.
The AMH22 profile covers all aspects of the MTA Abstract Service, as defined in clause 12 of ISO/IEC 10021-4,
when realized using the P1 protocol in an IPM environment.
The OSI upper layer services and protocols to support the Message Handling Systems functions covered by the
AMH22 profile are specified in subclause 1.3 of ISO/IEC ISP 10611-3.

(other forms of exposed interface, such as a standardized programmatic interface, are outside the scope of this version of
ISO/IEC ISP 12062).
3.2 Support classification
To specify the support level of arguments, results and other protocol features for this part of ISO/IEC ISP 12062,
the following terminology is defined.
NOTE - The requirements for support of arguments, results and other protocol features by an MTA are as specified in
ISO/IEC ISP 10611-3.

5 Conformance
This part of ISO/IEC ISP 12062 states requirements upon implementations to achieve interworking. A claim of
conformance to this part of ISO/IEC ISP 12062 is a claim that all requirements in the relevant base standards
are satisfied, and that all requirements in the following clauses and in annexes A and B of this part of ISO/IEC
ISP 12062 are satisfied.
5.1 Conformance statement
For each implementation claiming conformance to profile AMH22 as specified in this part of ISO/IEC ISP 12062,
a PICS shall be made available stating support or non-support of each option identified in this part of ISO/IEC
ISP 12062.
The scope of conformance to profile AMH22 is restricted to MTAs that support message transfer. A claim of
conformance to profile AMH22 shall confirm that the implementation supports profile AMH111 and shall state
whether the implementation also supports profile AMH112 (jointly referenced as AMH11 in this part of ISO/IEC
ISP 12062 where a distinction is unnecessary) as specified in ISO/IEC ISP 10611-3.
