Today is the day when Russian-language domain names have finally become open for registration for everybody, not just govenmental structures, trademark owners etc, so from now on these names' support will be very important for all users of ISPConfig in Russia.
As for 2.2.37 - now it truly supports adding a site with a such a name (thank you very much for this - I checked, and it worked), but sadly it doesn't work on the DNS side of things. So, if I try to add a DNS record and put such a name in SOA - I get "invalid domain name".
Is there a way to quick-fix it myself? I'm asking because I get literally dozens of requests for such domain names from my clients.
