local domains

[Sten Carlsen]

Yes, I do that.

Internal and external views have very different sets of hosts and names. 
E.g. mail..... is visible from inside and outside, with different IPs. 
This means that my laptop will read mail without ANY changes in setup 
wether it is on my own lan or anywhere else in the world.

Contrary to what I believed, you can have the exactly same names and 
structure or a very different in internal vs. external zone.

Use views, create one internal and one external view.

Good luck, for me it worked first time.
