bind 9.16.28 vrs. 9.18.2 (on freebsd) resolving foryoudecor.com

[Kurt Jaeger]

Hello,

we observed a strange behaviour for the domain foryoudecor.com,
when trying to resolve it using bind 9.18.2, using

dig -t mx foryoudecor.com

The bind log for 9.18.2 says:

May 11 12:00:14 ns named[96774]: fetch: foryoudecor.com/MX
May 11 12:00:14 ns named[96774]: DNS format error from 61.129.70.40#53 resolving foryoudecor.com/MX for 193.105.105.1#27259: server sent FORMERR
May 11 12:00:14 ns named[96774]: client @0x803bdcd60 193.105.105.1#27259 (foryoudecor.com): query failed (FORMERR) for foryoudecor.com/IN/MX at query.c:7657

so the domain was not resolvable.

bind 9.16.28 resolves the MX for this domain.

I tried to find out if it's an DNSSEC issue, using

https://dnsviz.net/d/foryoudecor.com

But the result looks very confusing to me. Apparently, somewhere,
a DNS server 'qhm3' comes into play (yes, that's the whole dns server
name!).

What can I do to debug this?
