标准范围

ISO/IEC 10021-4:2003 | ITU-T Rec.X.411定义了消息传输系统（MTS）抽象服务和MTS模型，并概述了MTS抽象服务。它定义了MTS抽象服务参数的语义和MTS抽象服务的抽象语法。ISO/IEC 10021-4:2003 | ITU-T Rec.X.411定义了消息传输代理（MTA）抽象服务，并改进了MTS的模型，以表明MTS由多个相互协作以提供MTS抽象服务的MTA组成。这里提供了MTA抽象服务的概述。ISO/IEC 10021-4:2003 | ITU-T Rec.X.411定义了MTA抽象服务参数的语义和MTA抽象服务的抽象语法。它规定了MTA执行的程序，以确保MTS的正确分布式操作。

ISO/IEC 10021-4:2003 | ITU-T Rec. X.411 defines the Message Transfer System (MTS) Abstract Service and the MTS Model, and provides an overview of the MTS Abstract Service. It defines both the semantics of the parameters of the MTS Abstract Service and the abstract-syntax of the MTS Abstract Service. ISO/IEC 10021-4:2003 | ITU-T Rec. X.411 defines the Message Transfer Agent (MTA) Abstract Service and refines the model of the MTS to show that the MTS comprises a number of MTAs that interwork with one another to provide the MTS Abstract Service. An overview of the MTA Abstract Service is provided. ISO/IEC 10021-4:2003 | ITU-T Rec. X.411 defines both the semantics of the parameters of the MTA Abstract Service and the abstract-syntax of the MTA Abstract Service. It specifies the procedures performed by MTAs to ensure the correct distributed operation of the MTS.
