Hi, I am trying to setup inbound email handling with mailgun and the http post API. Things I have configured: Mailgun API key. manual polling enabled = checked reply email address replay@mydomain reply by email enabled = checked Added a mailgun route: match_recipient(“.*@mydomain”) forward"(http://mydomain/admin/email/handle_mail&type=mime") MX record and am receiving replys in mailgun logs. Is there anything else I need to configure to fix “BAD CSRF”? Do I need a plugin or API web hook or something?

Does inbound mail use “handle_mail” endpoint when configured for mailgun?

I think I solved the Bad CSRF issue by adding user and api key to the URL but now I am seeing and error in the logs: admin/email_controller.rb error at line 86, missing required parameter "email’. Can I assume this is a json parameter that mailgun is not populating because of wrong API or something?

The logs: /var/www/discourse/vendor/bundle/ruby/2.3.0/gems/actionpack-4.2.8/lib/action_controller/metal/strong_parameters.rb:251:in `require' /var/www/discourse/app/controllers/admin/email_controller.rb:86:in `handle_mail' /var/www/discourse/vendor/bundle/ruby/2.3.0/gems/actionpack-4.2.8/lib/action_controller/metal/implicit_render.rb:4:in `send_action'

TL;DR: I don’t believe Mailgun’s mail forwarding will work as-is with Discourse. It doesn’t pass the email data in the right way and there doesn’t appear to be a way to change that on either end Mailgun nor Discourse. The detail Within Mailgun’s documentation there is a Django code example which indicates what is passed to the HTTP endpoint by mailguns forward functionality. An example payload at the bottom of this page confirms this. For reference here is the code sample: Consider this Django code: # Handler for HTTP POST to http://myhost.com/messages for the route defined above def on_incoming_message(request): if request.method == 'POST': sender = request.POST.get('sender') recipient = request.POST.get('recipient') subject = request.POST.get('subject', '') body_plain = request.POST.get('body-plain', '') body_without_quotes = request.POST.get('stripped-text', '') # note: other MIME headers are also posted here... # attachments: for key in request.FILES: file = request.FILES[key] # do something with the file # Returned text is ignored but HTTP status code matters: # Mailgun wants to see 2xx, otherwise it will make another attempt in 5 minutes return HttpResponse('OK') Note that this means that many POST parameters including sender, recipient, subject, body-plain, stripped-text and files as separate “chunks”. This is not what Discourse expects to be sent to the /admin/email/handle_mail endpoint - it simply wants the complete raw email as the email parameter.

Thanks a bunch, @DeanMarkTaylor. I’ll pursue different method then.

I followed these directions exactly, and am getting the following error at mailgun. Should I assume that I need to migrate away from mailgun to receive reply emails? Also, I’m confused what the mailgun api key is used for. Says it’s used to verify webhook messages. Can someone elaborate? { "severity": "temporary", "tags": [], "storage": { "url": "https://se.api.mailgun.net/v3/domains/reply.volyoom.fit/messages/eyJwIjpmYWxzZSwiayI6IjhiYTFjMTI0LWVhNmQtNDcxZC05MzU5LTNiNzhjZGY2MGJmYSIsInMiOiJkNDFhMjFlMDRmIiwiYyI6InRhbmtiIn0=", "key": "REMOVED" }, "delivery-status": { "attempt-no": 1, "description": "[\"BAD CSRF\"]", "session-seconds": 0.07819604873657227, "retry-seconds": 600, "code": 403, "message": "[\"BAD CSRF\"]" }, "recipient-domain": "REMOVED", "id": "QRcFjJ3NSKu0Hn9pfPnGyQ", "campaigns": [], "reason": "generic", "user-variables": {}, "flags": { "is-routed": false, "is-authenticated": false, "is-system-test": false, "is-test-mode": false }, "log-level": "warn", "timestamp": 1508087126.237296, "envelope": { "sender": "REMOVED", "transport": "http", "targets": "REMOVED/admin/email/handle_mail" }, "message": { "headers": { "to": "REMOVED Forum ", "message-id": "ADBE049D-0179-4B3C-813A-517A02741FBD@monroeresidential.com", "from": "Drew Friestedt ", "subject": "Re: [REMOVED Forum] [Zwift] This is a test topic with email reply" }, "attachments": [], "size": 7044 }, "recipient": "REMOVED/admin/email/handle_mail", "event": "failed"

Got it. I did see that but was hoping it was wrong. Can you recommend a solution that does work to deliver reply messages with mail-receiver?
