you can of course define 168.192.in-addr.arpa and put everything there.
the problem above looks like client with IP 192.168.16.3 asked the
named on server mail2 for 22.214.171.124.in-addr.arpa and
126.96.36.199.in-addr.arpa and got the responses from the internet.
You should serve those zones locally...
