The premise of the MailReader is that it is the first iteration of a portal application. This version allows users to register themselves and to create and maintain a set of accounts with various mail servers. When completed, the application would let users read mail from their accounts. This sample application does not allow sending and receiving of real emails, it collects user information and mail addresses only.
The MailReader application demonstrates registering with an application, logging into an application, maintaining a master record, and maintaining child records. This document walks through the pages, classes, and configuration elements needed to do these things.
The walkthrough starts with how the initial page is displayed, and then steps through logging in, adding and editing subscriptions, and creating a new registration.
