This is my case.

My ISP is hosting my company domain eg: dns internet dns service 
is hosted in their server. But locally here in my lan I hav a dns server 
(fedora c3) hosting the same domain: with its private ips 
reverse zone, dhcpd acualize the zone dinamically. But the smtp and pop3 
servers that I use are the same of my ISP (I don't have pop3 and smtp servers 
here y my lan), so doesn't exist in my lan, but how can I do 
for my dns local sever ask to another dns server for a record of the same 

like this: a pc ask por to my local dns server, my local dns 
server don't know about a but it asks to my isp dns server 
for a in their zone, if it exist in their zone 
turn back the ip.

Can I do this??? how??
