/**
* 郵件發送類
* 支持發送純文本郵件和HTML格式的郵件,可以多收件人,多抄送,多秘密抄送,帶附件(單個或多個附件),支持到服務器的ssl連接
* 需要的php擴展：sockets、Fileinfo和openssl.
* 編碼格式是UTF-8,傳輸編碼格式是base64
* @example
* $mail = new MySendMail();
* $mail->setServer("smtp@126.com", "XXXXX@126.com", "XXXXX"); //設置smtp服務器,普通連接方式
* $mail->setServer("smtp.gmail.com", "XXXXX@gmail.com", "XXXXX", 465, true); //設置smtp服務器,到服務器的SSL連接
* $mail->setFrom("XXXXX"); //設置發件人
* $mail->setReceiver("XXXXX"); //設置收件人,多個收件人,調用多次
* $mail->setCc("XXXX"); //設置抄送,多個抄送,調用多次
* $mail->setBcc("XXXXX"); //設置秘密抄送,多個秘密抄送,調用多次
* $mail->addAttachment("XXXX"); //添加附件,多個附件,調用多次
* $mail->setMail("test", "<b>test</b>"); //設置郵件主題、內容
* $mail->sendMail(); //發送
