I’ve installed for testing docker and discourse on my laptop. After the comand line: ./discourse-setup
I just put the informations in I’ve got from my sparkpost acount under SMTP relay. (I used the preconfiguration, which allowed to send 50 e-mails for testing)
As a sending e-mail I choosed: [discourse.yunity.com](http://discourse.yunity.com)
After then running with “localhost” discourse and register with an e-mail I get within sparkpost shown that theirs a e-mail coming in. ’
The problem is that it doesn’t send then an e-mail out.
That’s what I get as a message inside sparkpost:
“550 5.7.1 Unconfigured Sending Domain \<[discourse.yunity.com](http://discourse.yunity.com)\>”
"25 - Admin Failure "
Do I need to register my own sending adress to get it run or can it be aswell done with the settings from sparkpost?
If it can be done with the pre-settings coming from sparkpost, where could be the problem?

It only works with an own auth. sending domain.
