I am trying to send mail using code it works on locally but when i deploy it on live (Godaddy) hosting server
it gives me error
Here is the code

$mail = new PHPMailer();
$mail->isSMTP();
$mail->SMTPDebug = SMTP::DEBUG_SERVER;
$mail->Host = 'send.one.com';
$mail->SMTPAuth = true;
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 587;
$mail->Username = '[email protected]';
$mail->Password = '123456789';
$mail->setFrom('[email protected]');
$mail->addAddress('[email protected]');
$mail->isHTML(true);
$mail->Subject = 'Subject';
$mail->Body = 'This is the HTML message body';
if ($mail->send()) {
echo 'Message has been sent.';
} else {
echo 'Message could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
