        Vendor('phpmailer.class#phpmailer');
        Vendor("phpmailer.class#smtp"); //可选,否则会在class.phpmailer.php中包含
       
        $mail = new PHPMailer(true); //实例化PHPMailer类,true表示出现错误时抛出异常
       
        $mail->IsSMTP(); // 使用SMTP

          $mail->CharSet ="UTF-8";//设定邮件编码
          $mail->Host       = $email_set['Host']; // SMTP server
          $mail->SMTPDebug  = 1;                     // 启用SMTP调试 1 = errors  2 =  messages
          $mail->SMTPAuth   = true;                  // 服务器需要验证
          $mail->Port       = $email_set['port'];                    // 设置端口

          $mail->Password   = $email_set['email_pwd'];       //SMTP服务器的用户密码
          $mail->AddReplyTo($email_set['email'],$email_set['email_name']); //收件人回复时回复到此邮箱,可以多次执行该方法
          if (is_array($tomail)){
              foreach ($tomail as $m){
                   $mail->AddAddress($m, 'user');
