基于C/S的电子邮件简单收发系统设计与实现 摘 要 电子邮件作为互联网中交换信息广泛的通信工具之一，如今都已被广大用户接受。早期的电子邮件只是从一个计算机终端向另外一个计算机终端传送文本信息，而现在的电子邮件不仅可以发送文本信息，还可以传送声音、图片、文档等多种信息。很多邮件邮件客户端软件不断地被用户利用起来，例如outlook, Foxmail,但是这些邮件客户端对于很多用户来说却过于复杂。 为了方便用户快捷地收发邮件，本课题利用SMTP协议和POP3协议，经过前期对系统的需求分析和对相关协议的了解，设计并实现了简单的电子邮件收发系统。为了保证本系统功能的完整性，在实现该系统过程中，设计了邮件用户注册模块，当用户首次使用本系统时，须注册一个邮件账号，然后才能进行其他的操作。作为一个电子邮件客户端，邮件的发送与收取是其核心功能，本系统邮件发送块实现电子邮件的发送，支持邮件的单个发送和群发，在邮件收取块，实现了电子邮件的简单收取。另外还增加了地址薄管理块让用户更方便地管理自己的联系人，对联系人进行添加、修改、删除等。 关键词：电子邮件；SMTP；POP3；邮件收发系统
