I'm trying to use PHPMailer and it's not working. I even tried to contact Hostgator support, but the support passed me several doors, hosts to try and nothing worked. Finally, follow the code:
<?php
require 'class/PHPMailerAutoload.php';
$mail = new PHPMailer();
$mail->SMTPDebug = 3;
$mail->isSMTP();
$mail->Host = 'mail.dominio.com.br';
$mail->SMTPAuth = true;
$mail->Username = 'user';
$mail->Password = 'pass';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
$mail->Subject = $Subject;
$mail->setFrom('mail', $Subject);
$mail->addAddress('mail', $Subject);
$mail->isHTML(true);
$mail->Body = $body;
?>
The error returned is the one with $ mail-> SMTPDebug = 3;:
