Sometimes, the mail command is locked by the provider. You can try the following to get more information:

$success = mail('example@example.com', 'My Subject', $message);
if (!$success) {
    $errorMessage = error_get_last()['message'];
}

Taken from here

Or use a dedicated class like PHPMailer or similar.

the email address is stored in $_POST['email']. but, in your contact.php, row 5:

$mailFrom = $_POST['mail'];

Try replacing $_POST['mail'] with $_POST['email']

Hope it helps.

ps Also the label in your html code is for 'mail' too instead for 'email' like the input tag
