简述
当今世界电子邮件已经是网络生活中不可或缺的，相信每个认知网络的人都会有一个或多个自己的电子邮箱，人们通过电子邮件进行通信和交流，许多商家和组织机构也用电子邮件进行各种商业活动和业务联系，毫无疑问，电子邮件已经逐渐开始取代普通的信件，成为为主流的信件交流工具，带来的就是电子商务的发展。
VisualBasic6.0是微软开发的一款面向对象的程序设计语言，被广泛的应用各种系统应用程序的开发。有灵活，高效，易用，功能强大的等特点，所以用来编写电子邮件收发系统很合适。邮件收发系统是个人软件，利用个人电脑的outlook终端进行网络会话，相对的又比outlook邮件系统简单实用。当今网络上邮件系统多不胜数，几乎全是基于Web服务器的asp系统。用vb编写邮件系统没有Web服务器支持，所以不能像网络上那样有华美的画面和各种多媒体功能，用VB编写的只是一个邮件客户端。相比较而言，拥有的确是简洁实用和方便快捷，大大提高了我们的工作效率，节省了我们的时间。
