bind on standalone pc

[Jens]

I have a standalone PC with internet dial-up.
I'd like to use bind 8.2.4 for
a) caching
b) aliasing
c) resolving of non-ICANN names
 
b) means that I want to resolve "smtp" depending on the provider I 
use. For example if I use provider1, "smtp" should be resolved to 
smtpx.provider1.com.
 
And with c) I want to resolv names like www.bbc.news, i.e. I define 
some extrax (root-)servers.
 
Any ideas how the principal configuration should look?
To make the smtp-alias, do I create a master zone? A master zone for 
all internet?
And the non-ICANN servers are in a "."-zone of type hint?
 
Thanks!
