在检查连接的phpmailer时是否捕获了EOF

Question

    require 'phpMailerAutoload.php';

    $mail = new PHPMailer;
    $mail->SMTPDebug = 3;                               // Enable verbose debug output
    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'myhost';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'myusername';                 // SMTP username
    $mail->Password = 'mypassword';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 1060;                                    // TCP port to connect to
    $mail->setFrom('test@gmail.com', 'test');
    $mail->ishtml(true); // Set email format to HTML


    $mail->addAddress('test@gmail.com');    // Add a recipient  

    for($i=0;$i<1;$i++){
      $mail->Subject    = "test bulk email ".$i;
      $mail->Body       = "this is email ".$i;


      if(!$mail->Send()) 
      {
          $error_message = "Mailer Error: " . $mail->ErrorInfo;
      }
}

echo $error_message;

当我运行此代码时，我收到此错误：

连接：打开2018-03-05 09:24:25服务器 - >客户端：2018-03-05 09:24:25 SMTP注意：检查EOF是否连接2018-03-05 09:24:25连接：关闭2018-03-05 09:24:25 SMTP错误：无法连接到SMTP主机。

我该如何解决？
