Mail-receiver and/or Discourse are not posting email replies

Installation

I recently migrated discourse from AWS to DO Migrate from AWS to Digital Ocean with 2 containers, spaces and 2 CDNs - #3 by dfriestedt. Everything is working great, except for my mail-receiver.

When I reply by email and inspect the logs with ./launcher logs mail-receiver I get the follwing.

Looks like I’m getting a status of “sent” in the logs, however the reply is not showing up in discourse. Any thoughts here? This only started to happen after I migrated from AWS to DO.

I’ve investigated the logs by running the following. Looks like I’m getting some temporary failures for an unknow reason.

./launcher enter mail-receiver
mailq

Are you running the latest version of the mail-receiver container? You might be interested in this topic:

Some other things to check:

  • Does the API key in your mail_receiver config match with an API key in the Discourse admin UI?
  • Do you have any emails showing in the /admin/email/rejected logs?

Hello. Thanks for your reply

in mail-receiver.yml I have base_image: discourse/mail-receiver:release and do not see an error message about the mail-receiver being old. I’ve rebuilt the mail-receiver many times.

I do not see any email as rejected here: /admin/email/rejected
I did issue a new API key for user system with all privileges. I’m using that in mail-receiver.yml. I was thinking the API was the issue, but I’ve check the numbers match a few times.

Curious, I’m seeing no activity on the API I created

To test the network connection between the containers, you could try entering the container like

./launcher enter mail-receiver

And then try

wget -O - $DISCOURSE_MAIL_ENDPOINT

If the connection works successfully, you should see

wget: server returned error: HTTP/1.1 404 Not Found

If not, then double check the DISCOURSE_MAIL_ENDPOINT value in your config.

The level of my stupidity is insane. I deserve a massive dunce hat.

Connecting to discuss.360velo.com.com (199.59.242.154:80).

com.com… ??? I had the wrong DISCOURSE_MAIL_ENDPOINT. I had two .com.com in the URL and i should have been using https rather than http. Thank you very much for pointing me in the right direction.
