3.1.1 Abstract Data Model

This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to facilitate the explanation of how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document.

The Message Tracking Web Service Protocol is used to find and get message tracking reports on a primary account's mailbox on the server. The server maintains the reports and retrieves them as requested.

The client is not required to maintain the state of message tracking reports on the server and can retrieve the current report at any time. If more than one client is receiving a particular report, there is no requirement that the server lock the existing set of reports.
