smtp
/***********************************
PHP MIME SMTP 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 RCPT TO 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 $charset 改成你的默认 字符集
Html 正文中如有图片，请用绝对路径的引用 "httP://host/path/image.gif";
并连上网，以保证程序能读取到图片的数据信息
如果是通过表单提交过来的 Html 正文，请先用 StripSlashes($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 之类 的引用，直接把样式表定义放在
标签中
