No, if you want it to allow recursion, there isn't much else you can do.

Unless you don't. So it's up to YOU. So let me make myself a bit clearer and
you can decide The answers to the next two questions will answer how to
handle recursion:

1. Do you or others on your network need to use this server (by specifying
it's IP address in IP properties) to resolve domain names for your
workstation?
If yes, then you will need to allow recursion and that message aobout it
being an open server will continue. Not much you can do about that because
of what you need the thing for.

2. Is the DNS server's ONLY role is to host your public domain name for the
world to resolve only your public domain name and nothing else?
if yes, then disable recursion and that Open message should disappear.
