CAN/CSA-ISO/IEC ISP 12062-3-01

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.
 
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.
