after having read this article: Troubleshooting email on a new Discourse install I have followed all the steps mentioned, and yet the activation email is still not arriving.
I have the following entries:
DISCOURSE_SMTP_ADDRESS: a2ss19.a2hosting.com (I have also tried mail.dynomotion.com)
DISCOURSE_SMTP_PORT: 587 (I have also tried port 2525)
And I uncommented the line at the end of yml.app to read like this:
- exec: rails r "SiteSetting.email@example.com'"
Finally I tried this:
./launcher enter app rails r "SiteSetting.notification_email = 'firstname.lastname@example.org'" exit
But, like I said, no activation email.
