From what you've said below, they're quite right.

I think that is a legitimate use of my subscription to this list, and the list's raison d'être. Surely the list is not exclusively for individuals who know what they're talking about?..)

This list is for discussion of ISC's BIND.

This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall...

Let's assume that you've got a D-Link router which has a single public IP from your provider, and provides NAT translation for a private RFC-1918 subnet, and you've placed your webserver on a VM which lives behind that D-Link router.  If so, you will need to enable static port forwarding for 80/tcp to the VM running the webserver, or perhaps place that IP in the router's "Enable DMZ Host" section of the firewall config.

This is basic networking; it doesn't have any close relationship to either DNS or webservers.
