forwarder

[bind at col7.metta.lk]

Hi all,

I am behind a firewall and have no access to the Internet
I dial up my isp and get mail down by ppp login

My dns is working only because it is a requirement by qmail.

I saw a suggestion by Joseph S D Yao to use forwarders {}
to prevent bind from trying to use root.hints 
which take a long time (about 40 sec.)

I have tried with an empty root.hints file 
and it works much faster, 
but I see from the many mails on this list
that it is not the correct way.

Could you kindly let me know if this is the correct syntax
as I do not quite understand the use of forwarders,

/etc/named.conf
---------------

options {
    directory "/var/named";
    interface-interval 5;
    forward only;
    forwarders {};
};

/var/log/messages
