这个是对于
EMAIL发送系统(C#+基于SMTP认证) 1.0
的改版这个第一版是2002年11月写的，过了一年半了，才有人提意见，就修正了一下，因为后来做的项目一直用不上，也就没有注意到
前段时间有网友反馈了一些问题，这次主要做了一些修正
1,text模式下发往163的邮件内容不见了
2,如果用outlook接收而不是在网上看邮件的话,会发现正文内容,但其后跟着一些乱码.
3,一些新开通的邮箱收到的是乱码，如 *@126.com
4,修正了带附件的邮件，打开附件时内容混乱的问题
感谢 Lion互动网络论坛 的smhy8187和邮箱是 [email protected] 的朋友提供意见
欢迎大家提出修改建议，[注：]最好能把修改稿Mail给我一份，我们共同学习
