So find out what's making those AAAA queries and fix it. BTW, why is
that application querying your ISP's name server and not your own name
server?

The delegation for efori.com is broken. The .com name servers say this
is served by ns{1,2}.efori.com: 65.182.78.13{3,4}. [You should have
one of these servers on another net, but that's a different mistake to
be fixed.] Both of these two servers say efori.com is served by
dns1.efori.com, which is a name that doesn't exist. It may well be the
AAAA queries you're reporting are attempts by something to find IPv6
addresses for this non-existent name,

Nothing. If a NOHOST response is appropriate, that's what your name
server will return.
