* 名称:用Socket发送电子邮件
* 描述:本类实现了直接使用需要验证的SMTP服务器直接发送邮件,参考文章《用Socket发送电子邮件》作者:limodou
* 此文章比较早,他是用不用验证SMTP服务器发送邮件,现在基本上SMTP服务器都需要验证了,所以这个文章里的类
意义也不是很大!同时参考了[RFC 1869]和PHP手册!!和上文还有不同的是我用的不是fsockopen()函数
具体你自己看吧!!我刚刚测试通过了,很爽!!
其实把这个类再改写一下就可以直接发送带附件的邮件了,期待。。。我过几天给大家写出来!
我刚刚调试通过,如果你不恶意去捉弄这个程序,他还是很听话的,过些日子我会对他完善加上发送附件的功能!!

即使你的虚拟主机不支持MAIL函数,现在也不怕了!快快试试这个吧!
