It works fine on nssec.xelerance.com, which uses unbound plus all the
hardening settings, 0x20 and all:

host probsd.net 193.110.157.136
Using domain server:
Name: 193.110.157.136
Address: 193.110.157.136#53
Aliases:

probsd.net has address 66.93.16.108
probsd.net mail is handled by 20 zorak.probsd.net.
probsd.net mail is handled by 10 viisaus.probsd.net.
