How so ? a.example.com. IN MX 10 mx.example.com. b.example.com. IN MX 10 mx.example.com. c.example.com. IN MX 10 mx.example.com. d.example.com. IN MX 10 mx.example.com. mx.example.com. IN A 192.0.2.1 mx.example.com. IN AAAA 2001:db8::1 1.2.0.192.in-addr.arpa. IN PTR mx.example.com. 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa. IN PTR mx.example.com. Why does your MX have to live in the same zone as what it's MX'ing for ?
