You only need a recursor if you have computers that want to use your IP
address to gain information about domains that are not yours.

So unless there are unix computers with the ip address of your nameservers
in /etc/resolv.conf, or there are windows or apple machines configured to
use your IP address as their resolver, you don't need a recursor.

These days this is what we call a 'small' powerdns installation :-)

This is correct. But regular authoritative servers do not need this feature.

Good luck!
