zone "xuz.com" {
type=master;
file="db.xyz";
}
zone "inside.xuz.com" {
type=master;
file="db.inside.xyz";
}
and in db.xyz
inside IN NS ns.xyz.com.
if you want outsiders to be able to resolve machine.inside.xyz.com
See the _DNS and BIND_ chapter on parenting.
Re: email, just turn on masquerading in sendmail.cf to strip all
but xyz.com on outgoing mail.
