求一邮件系统的源代码
如题目,从网上找了一些,都感觉不太好用,请问谁有.NET的源码啊?
小弟先在这谢谢大家了~~
这个程序是我自己写的,是通过Soket进行连接的,由于时间仓促所以只写了发送邮件;源程序如下,在这里我只转载了源代码:

class MailNotice
{
////////////////////////////////////////////////////////////////////////////////////////////
//类名： SendMail
//功能： 主要实现了邮件的发送功能，是通过SMTP协议实现的
//基本需求： 需要IO,Net,Net.Sockets命名空间的支持;
//说明： 邮件发送的内容是固定的，硬编码在了代码中，可根据需要自动修改
