Webmail Module Requirements

I. Introduction

This document describes the requirements for the ACS Webmail module. The Webmail module provides a web-based email service.

II. Vision Statement

Web-based email is a convenient and highly accesible way of communicating over the internet. Because web-based email only requires a browser, it is accesible from almost any connected computer, and because all the messages are stored on a server, it is easy for the user to check his or her mail from a number of different machines. The Webmail module aims to achieve the following goals:

• Provide a reliable web-based email service
• Provide a simple, but powerful user-interface
• Provide a service competitive with other commercial web-based email services
• Provide a scalable data-module and efficient implementation

III. System/Application Overview

The Webmail module consists of:

• An interface for the user including:
  • Browsing available messages
  • Reading specific messages
  • Composing outgoing messages
  • Customizing the user interface and functionality of the module
• An interface for the administrator which includes:
  • Choosing domains handled by Webmail
  • Adding and deleting users in those domains
  • Viewing a list of recent Webmail errors

IV. Use-cases and User-scenarios

The Webmail module is intended to provide arsDigita employees and community members a web-based email service. Users would be community members who are looking for a convenient mail-service which would seamlessly integrate with other ACS tools, or people looking to escape highly commercialized mail-systems like Hotmail or Yahoo! Mail.

Eventually, Webmail will surpass Hotmail in usability and flexibility. It should also, in the future, at least match, if not surpass Yahoo! Mail in usability, flexibility, and features.
