- Come back to control panel and choose "No" on "Custom DNS records" at this moment I supposed that resolver search remotly but dig give to us same result
So now, you agree now that the custom DNS resource record feature has nothing to do with your request for enhancement That's a good starting point. As I said in my previous answer, assumptions are just unhelpful. This just make us losing time
What you want (Enhancement request), is the ability to deactivate i-MSCP DNS management for specific domains, even when Bind9 is installed and set as local DNS resolver. Of course, this is possible. A simple switch ON/OFF for the DNS feature (on a per customer basis or per domain basis) should do the trick.
Does we agreed each other?
