SMTP works with test emails but not with new activations

I followed the instructions here Install Discourse Forum on Ubuntu 18.04 Without Docker and got a working Discourse set up with minimal issues. Upgraded to the latest version and everything seems fine except emails.

The admin page SMTP test works … I can send out emails just fine from there. But when testing user registration emails do not go out - in fact there is nothing in admin->emails->sent being logged (other than the test messages) admin->emails->skipped is empty (as is bounced received and rejected-- all empty)

As near as I can tell production.log does not have any related error and the admin->logs->Error logs has nothing related either.

This smells like a permissions problem or a missing temp directory … but nothing in the logs makes it rather difficult to figure out what’s going on.

Any thoughts or ideas, is there a way to turn on more logging to hunt down whats going on internally?


is there a reason why you used Install Discourse Forum on Ubuntu 18.04 Without Docker and not the official install guide ?

I really didn’t want to deal with having to manage a docker container, or the additional overhead it brings on a perfectly good operating system that would be dedicated to this task. I also have a Postgress system already geo-diverse that I can use vs an on-instance one … All these normal %snix things I can handle but the opacity of discourse has me a bit baffled at the moment. I’m pretty sure I can figure it out with strace but I was hoping to skip those hour or so of debugging by asking here :wink:

Just on the off-chance it’s something simple, have you checked you’ve not accidentally set disable emails in the admin settings?

Good idea to check that, but seems to be “No” which is “enabling emails” I think –

in ~/log/production.log I do get the following so its making it this far

Started POST “/u/action/send_activation_email” for X.X.X.X at 2022-02-10 21:45:52 +0000
Processing by UsersController#send_activation_email as /
Parameters: {“username”=>“”}
Rendered text template (Duration: 0.0ms | Allocations: 3)
Completed 200 OK in 29ms (Views: 1.6ms | ActiveRecord: 0.0ms | Allocations: 7196)

found this old related thread, if its true than the test email service and the normal email services are different Test emails work fine but nothing else

I think i found the solution

Did that work?

I’m afraid I only have experience with the standard install, so can only chip in curiosity contributions. :slightly_smiling_face: Are you trying to set up a live production site?
