So I updated ISPConfig to use the ns1 and ns2 from mydomain.com. Now I updated the mydomain.com entries as:
dancingmokey.com MX Priority 5 mail.dancingmokey.com
dancingmokey.com MX Priority 0 server.dancingmokey.com
dancingmokey.com A 184.108.40.206
Then I created subdomains.
This one is created as a new site in ISPConfig:
images.dancingmokey.com A 220.127.116.11
And this is where ISPConfig is setup on the server:
So, should that about do it?
server.dancingmokey.com A 18.104.22.168
