You have one of these two options set on your SMTP Transport:
hosts_try_dane
hosts_require_dane
Each of those takes a host-list, so might currently look like:
hosts_try_dane = *
You can change that to look like:
hosts_try_dane = !*.gov.hk : *
If the host-list references external files, take a look at those.
