I have the same question. I searched for an answer and I found this topic.

More specifically I wonder whether here we should put the same subdomain the Discourse instance has ([discourse.example.com](http://discourse.example.com)) or the domain ([example.com](http://example.com)). And whether this is something related to the SMTP configuration at all.
