Hostgator makes everything difficult. I had a lot of issues with a client. They told me to use phpmailer and added the client to the whitelist. It worked. Now I have another client and my file contact.php was not loading and returning 409. I changed all the id names with the word contact to form and the contact.php to mensagem.php and the file loaded. But not working yet. Maybe adding to whitelist once again. Tell you later.
