Your configuration looks correct, the problem seems to be with your ISP.
They haven't delegated the first domain, and the other two domains are
delegated to the nonexistent host ns1.emind.com.

The first one actually appears to be delegated as
1-31.80.209.63.in-addr.arpa (not 0-31 as you wrote), and it's also
delegated to the nonexistent host ns1.emind.com.

With classless in-addr delegation, even queryng the box directly doesn't
work if the delegations and CNAMEs aren't correct.  Level3.net has the
CNAMEs, you just need them to correct the delegation to point to your
server instead of ns1.emind.com.  If ns1.emind.com *is* your server, you
need to get an A record for it added to the emind.com domain, which is
hosted by Network Magic Unlimited.
