I am trying to sent email using SMTP (PHP Mailer). I am using the aws SMS service. Below is my code:

$mail->isSMTP();
$mail->Host     = 'email-smtp.eu-west-1.amazonaws.com';
$mail->SMTPAuth = true;
$mail->Username = '---';
$mail->Password = '---';
$mail->SMTPSecure = 'tls';
$mail->Port     = 587;

I gat the following result from Debug error:
