/**
* 郵件傳送類
* 支援傳送純文字郵件和HTML格式的郵件，可以多收件人，多抄送，多祕密抄送，帶附件的郵件
* 需要的php擴充套件，sockets和Fileinfo。
* @example
* $mail = new MySendMail();
* $mail->setServer("XXXXX", "[email protected]", "XXXXX"); 設定smtp伺服器
* $mail->setFrom("XXXXX"); 設定發件人
* $mail->setReceiver("XXXXX"); 設定收件人，多個收件人，呼叫多次
* $mail->setCc("XXXX"); 設定抄送，多個抄送，呼叫多次
* $mail->setBcc("XXXXX"); 設定祕密抄送，多個祕密抄送，呼叫多次
* $mail->setMailInfo("test", "<b>test</b>"); 設定郵件主題、內容
* $mail->sendMail(); 傳送
