That's very helpful information. Is there any way to configure bind to
avoid using those nameservers? It doesn't appear as if it's currently doing
that on its own. I'm also very surprised that such an organization would
have such a poorly configured DNS. Is that common?

Here's McAfee's blocklist service that also has numerous problems,
including name servers that don't even respond.

I'm also seeing similar issues with other name servers as query-errors:

27-Nov-2022 15:09:51.471 query-errors: client @0x7fd19e38cb68
127.0.0.1#53460 (us-smtp-delivery-100.mimecast.com.sa.fmb.la): query failed
(timed out) for us-smtp-delivery-100.mimecast.com.sa.fmb.la/IN/A at
../../../lib/ns/query.c:7729

Is there any way to display the name server that failed with these queries
so I can research further?
