Some years ago i had not competent DNS provider, which resulted
in similar issue -- eg. unbound refused to process that record(s)

non-terminal records and PowerDNS with SQL backend (or so).
As it happens it is also unbound that we are using. Here are the
particular debug logs for the query in question:

We're currently working on summarizing the situation and will then ask
the client to raise a ticket with Proofpoint.
Many thanks for all the comments and suggestions.
