What is the logic for emails in Discourse notifications on Cloudron?
I think I got it with changing the root email.
But I am unsure how to configure the Discourse notification mail addresses.
I am getting error:
550 Authenticated user firstname.lastname@example.org cannot send mail as email@example.com
There are quite a few settings under: /admin/site_settings/category/email
Is there a guide what to set how?
