Hi Chris, this looks interesting, I'll do some testing and report back!

Thank you,

No, not unless you want to monkey around with static zones and $INCLUDE directives -- something like this:

Internal zone file:

$TTL 86400	A

External zone file:

$TTL 86400	A

where the *.zone.apex files look something like this:

$TTL 86400
@	SOA	[... 7 data fields ...]
	MX	10

This way, you mostly maintain 3 files of DNS records for the zone -- external, internal, and common. Note that this is not compatible with dynamic zones.

If you need to support dynamic zones (and who doesn't, these days?), you're out of luck.
