/***********************************
PHP MIME SMTP ver 1.0 Powered by Boss_ch， Unigenius soft ware co. Ltd
All rights reserved, Copyright 2000 ;
本類用 PHP 通過 smtp sock 操作發送 MIME 類型的郵件，可以發送
HTML 格式的本文、附件，採用 base64 編碼
本版本是針對個人的發送，與多人群發版本不同的是，每發送到一個人，就重新進行一次編碼，在接收端的使用者看來，只是發送給他一個人的。
針對多人群發的情況，只發送一次，通過多個 RCPT TO 命令發送到不同的人信箱中，
說明：
請把 $hostname 設為你有許可權的 預設 smtp 伺服器或是在 new 時指定
把 $charset 改成你的預設 字元集
Html 本文中如有圖片，請用絕對路徑的引用 "image.gif";
並連上網，以保證程式能讀取到圖片的資料資訊
如果是通過表單提交過來的 Html 本文，請先用 StripSlashes($html_body) 把本文內容進行預先處理
Html 中用到的樣式表檔案，請不要用 <link >之類 的引用，直接把樣式表定義放在
<style></style>標籤中
轉載請保留此著作權資訊， Bugs Report : boss_ch@china.com
