SMTP連接（）失敗phpmailer

   require 'PHPMailer-master/PHPMailerAutoload.php'; 
       $mail = new PHPMailer(); 

       $mail->SMTPDebug = 1;        // Enable verbose debug output 

       $mail->isSMTP();          // Set mailer to use SMTP 
       $mail->Host = 'smtp.mail.yahoo.com'; // Specify main and backup SMTP servers 
       $mail->SMTPSecure = "ssl"; 
       $mail->SMTPAuth = true;        // Enable SMTP authentication 
       $mail->Username = 'myemail';     // SMTP username 
       $mail->Password = 'mypass';       // SMTP password 
      // $mail->SMTPSecure = 'tls';       // Enable TLS encryption, `ssl` also accepted 
       $mail->Port = 465;         // TCP port to connect to 

       $mail->From = '[email protected]'; 
       $mail->FromName = 'abc'; 
       $mail->addAddress('[email protected]');    // Name is optional 


       //$mail->isHTML(true);         // Set email format to HTML 

       $mail->Subject = 'Here is the subject'; 
       $mail->Body = 'This is the HTML message body <b>in bold!</b>'; 
      // $mail->AltBody = 'This is the body in plain text for non-HTML mail clients'; 

       if(!$mail->send()) { 
        echo 'Message could not be sent.'; 
        echo 'Mailer Error: ' . $mail->ErrorInfo; 
       } else { 
        echo 'Message has been sent'; 
       }
