/***********************************
PHP MIMESMTP ver 1.0 Powered by Boss_ch， Unigenius soft ware co. Ltd
All rights reserved, Copyright 2000 ;
本类用PHP通过smtp sock 操作发送MIME 类型的邮件，可以发送
HTML 格式的正文、附件，采用base64 编码
本版本是针对个人的发送，与多人群发版本不同的是，每发送到一个人，就重新进行一次编码，在接收端的用户看来，只是发送给他一个人的。
针对多人群发的情况，只发送一次，通过多个RCPTTO命令发送到不同的人信箱中，
说明：
请把$hostname 设为你有权限的默认smtp 服务器或是在new 时指定
把$charset 改成你的默认字符集
Html 正文中如有图片，请用绝对路径的引用
并连上网，以保证程序能读取到图片的数据信息
如果是通过表单提交过来的Html 正文，请先用StripSlashes($html_body)把正文内容进行预处理
Html 中用到的样式表文件，请不要用<link >之类的引用，直接把样式表定义放在
<style></style>标签中
