Network - IPM (Interpersonal Messaging)

In the ITU X.400 series of recommendations for message handling systems (MHS), one of the two major categories of message handling, with the other being a message transfer system (MTS). IPM represents a type of message handling for use in ordinary business or private correspondence. The handled elements-interpersonal messages-consist of heading and body components. Headings are made up of fields (such as name, address, IP Subnet Addresses 490 IPM (Interpersonal Messaging) subject) and values for these fields. The actual content of a message makes up the body. The entire content can be broken into smaller chunks (body parts), each of which may be manipulated separately. The interpersonal messaging process is assumed to take place in an IPME (Interpersonal Messaging Environment) under the control of an IPMS (Interpersonal Messaging System). In IPM, users exchange messages and replies over the IPMS, as depicted in the figure "IPM and its components"). As shown in the figure, users in IPMEs have three main kinds of capabilities: Originate, in which the user initiates a message transmission or exchange. Various types of originate actions are possible-including a probe to determine whether anyone is listening, and transmitting the start of a message. Receive, in which the user receives a message or a probe through the IPMS. Manage, in which the user can change material associated with the user's headings (name, address, etc.).
