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 connect.app@root-domain.de cannot send mail as discourseadmin+verp-9cf967b0413a4792c2e2aec8cdbb7805@rootdomain.de

There are quite a few settings under: /admin/site_settings/category/email
Is there a guide what to set how?

I was able start fairly fresh. Cleaned WP and exported > imported to Ghost. Website is sorted.

Discourse I haven't tried yet. Thank you for your suggestions on that.

Mails are also fine. So, now I am setting up Etherpad and all the other goodies.

@msbt
I tried a simple restore of my backup from my instance at DiscourseHosting and it worked flawlessly.
The versions the same.

@nebulon Yes, thank you. I found it!
