Define a domains addresses sole in terms of another

[John Steel]

Thanks for your help. Do you mean like this? What do I do with the IP 
addresses?
Why are there 3 NS recs now? Why is there no ref to example1 - thats the 
link I was trying to build.
I guess I misunderstood :-(

$TTL    86400

@       IN      SOA     ns.example2.com. system.admin.example2.com. (
                        1132657947      ; Serial
                        10800   ; Refresh
                        3600    ; Retry
                        604800  ; Expire
                        86400 ) ; Minimum

@                         IN NS      example2
@                         IN NS      example2
@                         IN NS      example2

example2                  IN A       1.2.3.4
@                         IN A       1.2.3.4

www                              IN CNAME   @
webmail                          IN CNAME   www
ftp                              IN CNAME   www
mail                             IN CNAME   www

@                         IN MX  10  example2
