I’ve just tried setting up Mail-in-a-Box, and now my entire server has no DNS, meaning that I can’t install any packages, or connect to anything else. I can still SSH in, but can’t download anything I don’t have the IP for.
Can you provide some details about your Provider etc.? Is there a Hardware Firewall?
Try to restart the box or re-run the setup with sudo mailinabox
