Hi, I have a working multi server setup of control / web server, a mail server and 2 dns servers. what i want to achieve is another web server with its own emails and databases so i can rent that to a customer, so it is self contained. I did try standalone and get my dns servers todo dmarc, spf and dkim, but as the client, web site, email domain and mail boxes are not created or configured via the control panel- it didnt 100% work. cannot create dmarc records and using mxtoolbox.com fails tests. what would the best route be for me to do this?
