For anyone looking for a workaround to easily debug SMTP issues on your Drupal environment. I was able to get the output by inspecting the POST request in my web developer console when sending a test email from /admin/config/system/smtp. If you right click on the POST request, Copy -> Copy as cUrl. Then paste that in your terminal, you will see the SMTP Debug output.
