邮件系统客户端的设计与实现
摘要
随着计算机网络的高速发展,人与人之间信息传输量越来越大,传输时间也越来越短。在这计算机技术和Internet广泛普及的时代,电子邮件扮演了一个非常重要的角色。通过电子邮件,人们可以方便的进行文字、图片、视频、声音、数据文件等的传递。而电子邮件系统客户端(MailBox)是一款类似于微软OutLook Express和国产FoxMail的电子邮件客户端软件,它的设计与实现遵循简单邮件传输协议SMTP和邮局协议POP3。本设计的目的主要在于实现用户对众多邮箱的统一管理,提高邮件收发速度,实现邮箱多账户管理,邮件分析析和管理,联系人管理,实时收信等功能。本设计是以VS2008为开发环境,以SqlServer2000作为后台数据库,同时结合了开源邮件协议组件LumiSoft.Net.dll开发出来的C#窗体界面应用程序。它的设计与开发严格遵守软件设计开发流程,包括可行性研究、需求分析、总体设计,详细设计和测试等。相对网页邮箱而言,MailBox具有良好的可操作性、友好的界面风格以及更快的处理速度,支持用户多邮箱账号的统一管理,支持离线编辑、修改和阅读邮件,使用户对邮件管理更加快捷方便。使用客户端软件收发邮件,登陆时无需关注网站页面的避免下载页面内容,登录速度会更快;使用客户端软件保存收到的和已经发送过的邮件在自己的个人电脑中,不用网络就可以对电脑中的所有邮件进行阅读和管理。客户端同时支持多用户,多邮箱账户和其他POP3支持,对邮件的管理更快捷更方便。本文描述的系统具有简单明了、操作方便,随时扩充的特征。经过实际的测试和使用证明,系统具有很好的实用性。
With the high speed development of computer networks, the amount of information transfer between people is increasing and the transmission time becomes shorter and shorter. In this computer technology and the Internet widely available era, E-mail plays a very important role .By e-mail people can asynchronously transfer text, pictures, video, voice, data files, etc. However, e-mail system client (Mailbox) is an e-mail client software similar to Microsoft's Outlook Express and domestic Fox Mail. Its design and implementation followed the Simple Mail Transfer Protocol and Post Office Protocol. The main purpose of this design is to achieve a unified user management of multiple mailboxes, improve the e-mail receiving and sending speed, analysis and management of e-mail, administrative contact and receive e-mail in real time and other functions. The design is based on Microsoft Visual Studio 2008 as the development environment, SqlServer2000 as a background database, combined with the open source components LumiSoft.Net.dll mail protocol developed by C# informs. Its design and implementation strictly abide by the software development process, including feasibility studies, requirement analysis, general design, and detailed design and testing. Contrast Web mail, Mailbox has good maneuverability, style-friendly interface and faster processing speed, enabling users to unified management of multiple email accounts, support for offline edit, modify, and read messages, allowing users quicker and more convenient for mail management. Use e-mail client software, landing page content without downloading sites, faster; using the client software has been received and sent through the mail are stored in your computer without Internet access can read the old messages and management. At the same time multi-user, multi-mailbox accounts, and more POP3 support, mail management faster and easier. This paper describes the system with simple, easy to operate, at any time expansion characteristics. After the actual testing and use of proven, the system has good usability.
