Many hostnet.nl domains emit incorrect denial of existence NSEC3
records for DANE TLSA queries.  This will cause email delivery
problems to your customers' domains if not resolved by fixing the
nameserver software.  My (surely incomplete) list of affected
domains is below.

The newly updated (thanks Casey!) dnsviz.net site now gives a very
clear picture of the problem (just "mouse over" the NSEC3 record
box).  The NODATA response is not accompanied by any NSEC3 records
that match the hash of the Qname, rather the NSEC3 records prove
NXDOMAIN, but the RCODE is incorrectly NOERROR:


Queries for the TLSA records of all the MX hosts below similarly
fail validation.  What and when might be done to fully address this
