Bind Problem :(

[Mahmood Javanmardi]

Suppose that We have "foo.com" domain that is mapped to a class C network say 200.200.1.0/24
But Our Mail Server is Somewhere else, ("mail.foo.com") with another IP address say 64.239.82.55 that is shared between some mail server and maintain by somebody else who have their own DNS server.
I have created all the nessecary files to run bind means:
db.cache,  db.200.200.1, db.127.0.0, db.foo and also named.conf
But I don't know what I should append to these configuration to support my mail server.
Waiting for your help,
Thanx in advance
