使用PHPmailer发送邮件无法在实时服务器

Question

如果我使用Gmail smtp凭据正常工作，并在上线服务器后它无法正常工作。当我使用godaddy网络邮件时，它无法在localhost或实时服务器上运行。

这是我的PHP文件。

<?php
    $data = json_decode(file_get_contents("php://input"));
    $Cust_Email = $data->Cust_Email;
    $result = array();
require 'vendor/PHPMailerAutoload.php';

$mail = new PHPMailer;


$mail->isSMTP();                                   
$mail->Host = 'relay-hosting.secureserver.net';  
$mail->SMTPAuth = true;                              
$mail->Username = 'orders@washbucket.info';                 
$mail->Password = '******';                           
$mail->SMTPSecure = 'ssl';                           
$mail->Port = 25;                                    

$mail->setFrom('orders@washbucket.info', 'Admin');
$mail->addAddress($Cust_Email);    

$mail->isHTML(true);                                  

$mail->Subject = 'Welcome To User.';
$mail->Body    = 'This is greating from Admin';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
     $result = '_FAIL';
} else {
    $result = '_SUCCESS';
}

echo json_encode($result);
?>
