Message tracking is the ability to find out the path that a particular message has taken through a messaging system and the current routing status of that message. This document provides a model of message tracking that can be used for understanding the Internet-wide message infrastructure and to further enhance those capabilities to include message tracking, as well as requirements for proposed message tracking solutions.
