Configure the system resolver to be *authoritative* for the IP

multiple /24s, ...
Unbound, for example, can be configured to nxdomain specific names and
their subdomains (simpler than a proper empty zone).

Thanks, I'm not currently running a DNS resolver on the server, but if the
unresponsive PTR record issue persists I'll look into Unbound or maybe
Dnsmasq.
dnsmasq is forwarding resolver and as such a bad idea for a mail server.
