Web Mail收发系统设计与开发
摘要
互联网络技术的不断发展,电子邮件服务已经成为人们基本的信息交互手段,也是网络服务中最早和最基本的服务之一。传统邮件系统大多是基于C/S结构,如Lotus notes、Microsoft Exchange Server等,这些邮件系统占用相对较多的服务器资源,对服务器性能有更高的要求,同时也增加了管理负担。并且,由于不同服务器需要特定的客户端软件,增加了系统的开发和管理成本。
基于Web的邮件服务提供了更快捷、高效的服务,使得新一代的Web Mail能解决传统邮件的不足之处。本文设计并实现的邮件收发系统基于B/S模式,以组件技术为基础,,分别调用Mailmessage,Mailattachment和SMTPmail方法,实现以Web网页的形式收发电子邮件,用户只需要通过Web页面就可以实现带附件邮件的发送。
本论文分为四个部分,分别是:一、选题意义及系统构成;二、介绍邮件收发系统的工作原理、优缺点及开发环境;三、程序编码及页面设计; 四、对Web邮件系统进行测试并获得测试的结果。

Abstract
With the development of the technology, mail service has been a basic mean of munication, which is also one of the earliest and the most basic services of the . However, traditional mail services is based on client and server, for example, Lotus notes, Microsoft Exchange Server, which have used more resources of the server, thus, affect the capability of server and need high performance of server. Meanwhile, each server needs special client, which increases the cost of developing and managing the system.
Based on Web mail server system provides faster, more efficient Web mail services, with the strong capability, the new generation of the Web mail can change the disadvantage of the traditional mail. This paper designs and implements a Web mail receiving-sending system, which is based on browser and server as well ponents technology, sending mails through Web and users can use it to send mails with attachments.
This paper is divided into four main modules, respectively are First, introduction the background of the selecting the topic as well as the constitution of the system; Second, introduction of work principle, superiors and inferiors and the developing environment of the
