Please note that SOGo only works with netcup domains.
Make sure that you are not using an existing mail server with the selected domain. Otherwise, you will lose access to the existing mail server.
Please note that after assigning a domain, the MX record is set automatically and existing MX records are overwritten. SPF and DKIM records, which verify you as the sender, are not set automatically. Adjust your DNS records manually: DNS Records
