title: Rails Exception notifier is not working
body: <p>I installed the exception notification plugin from <a href="http://github.com/rails/exception_notification/tree/master" rel="nofollow noreferrer">http://github.com/rails/exception_notification/tree/master</a></p>
  
  <p>I can confirm that my ActionMailer is working as I received emails from other process. Although, I can see the notifier sending the email in the log (Sent mail to my@email.address )
  and the email address was written correct, I didn't get any emails about the exceptions.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks</p>
