"Discourse::NotFound" error when click "Email Type" field on admin/email/bounced

I think clicking on an “Email Type” field, e.g. user_watching_first_post is meant to display details of the bounce message received from the intended recipient.

But on my self-hosted site I get the error message stated above. Is there anything I can do to fix this?


That is correct. I’ve just checked this on my hosted Discourse site and it’s working without any problems. If your site is on the latest version of Discourse, I’m wondering is the issue is related to how your mail server handles forwarding the bounce message.

Thanks. For outgoing mail I’m using Mailgun. I think I used Discourse’s recommended settings.

For incoming mail I’m using this Straightforward direct-delivery incoming mail But I’ve never updated it since installation - might that be the problem? As it’s ./launcher rebuild app for Discourse, is it ./launcher rebuild mail-receiver?

Yes, that’s how to upgrade it. It’s been a while since the last update, I think, but a good first stop) step would be to upgrade it and discourse.
