smtp - phpmailer with godaddy host

I have trying to make a smtp connection by using phpmailer and it host on godaddy, it show Connection refused (111) after I try below code. Am I doing something wrong?

<?php
    require 'PHPMailerAutoload.php';

    $mail = new PHPMailer();

    $mail->SMTPDebug = 2;
    $mail->Debugoutput = 'html';

    $mail->IsSMTP(); 
    $mail->Host = 'smtpout.asia.secureserver.net';
    $mail->Port = 465;
    $mail->SMTPSecure = 'ssl';
    $mail->SMTPAuth = true;

    $mail->Username = "username@domain.com";
    $mail->Password = "mypassword";

    $mail->setFrom('username@domain.com', 'sender');
    $mail->addAddress('receiver@domain.com');

    $mail->Subject = 'Here is the subject';
    $mail->Body     = 'TEST';
    $mail->AltBody = 'This is a plain-text message body';

    if (!$mail->send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;
    } else {
        echo "Message sent!";
    }
?>
