Create Supervisor And Customer
In order to be able to setup a first domain, we need to create at least one Supervisor and a related Customer.

Create Domain and Connect To Your Mailserver
To create a first domain, navigate to "Domains" and click on the "Add new domain" button.

Select the previously created Customer and enter the domain FQDN into the "Domain Name" field.
In case this domain should be relayed to a smarthost, also enter its FQDN or IP-Address into the "Host/IP" field under "Next Hop".
Authentication credentials, target port and TLS offer behaviour can also be set here.
Save the domain and it will appear in the domain table

In order to allow relaying to the previously configured Next Hop host, we need to set a Mail Rule to allow it.
Navigate to "Mail Rules" and click on the "New Map Entry" button to access the form:

Select "connect:" in the first dropdown and enter your target FQDN or IP-Address into the second input field.
Then click on "Add Mail Rule" which will open a form where sub-rules can be configured

Set the "Relay" subkey to "Strict" and save.

Your Mail Rule will appear in the table and the MTA will allow relaying to the set host.
