So if my server is authoritative for MyDomain.com, should Joe Sixpak be 
able to resolve it via whatever DNS he's using, as mine is currently set up?

Do I need to change it to

|allow-query     { any; };|

in order to allow that to happen?  Will my restriction on recursion keep 
the riffraff to a minimum?

Thanks.
