The settings can’t be modified in the web interface, and given that they’re pretty much fire-and-forget settings, it’s unlikely they’ll be brought into the web interface any time soon.
To make the change, do the following once you’re in your droplet as root:
- Run
cd /var/discourse - Run
nano containers/app.yml - Edit SMTP-related settings as needed
- Exit out of the editor with Ctrl-X (and select ‘Y’ to save changes)
- Run
./launcher rebuild app - Wait a few minutes for the rebuild to complete
- …
- PROFIT!
