MX record

[geeta at cdfd.org.in]

Hello ,

We have firewall (used for natting) and inside our LAN only
we have in one machine where public IP natted to private IP
the DNS server and email server. Now I want to forward the 
emails to a different machine.

Now my qn is can the email server be given the private IP or should it 
also have public IP natted to private IP
 
present entry in named.hosts

IN MX 100 www.cdfd.org.in.
cdfd.org.in In A 210.212.212.3

Now I want to change to

IN MX 100 mail.cdfd.org.in
mail.cdfd.org.in IN A ?

? --> can be a private IP or not 



pls clarify my doubt

Thanks
