Is it possible to use an existing local DNS server to host the local copy of the domain DNS records - the one that points to a local resource, e.g. mail.localdomain, rather the external view of the same server, e.g. mail.mycompany.com?

Have I got this right? With Split-DNS, the local DNS and the external DNS both claim to be authoratative about mycompany.com; the local DNS has private IPs for local resources (192.168 etc) and the external DNS has external IPs for external resources (69.... etc)?

What about the local reverse lookup of mail.mycompany.com? DO I point 192.168.X.X at mail.mycompany.com or mail.localdomain?

Sorry if this has been asked to death.
