I have a working installation of Discourse setup. I have a test mailgun account setup that is working with this installation. Discourse is successfully sending out verification emails and topic replies. However I am not sure how to properly setup reply by email. For instance when I try to reply to a topic by using the “reply to this email to respond” contained in the email, I get an error message from Mailgun:

A message that you sent could not be delivered to one or more of its  
recipients. This is a permanent error. The following address(es) failed:

replies+randomcharacters@discoursedomain

What other settings do I need to make to my Discourse (or Mailgun setup) installation to allow this?

Any help is appreciated. Thanks in advance.
