Getting greylisting going on a new Debian box

Hi,

Just setting up relaydelay and I am finding that relaydelay is failing 
clients on the local LAN.

I have attempted to put 192.168.1 into the database but to no avail.

What should the mysql syntax be for 192.168.1.0/24 not to be blocked 
ever please?

Does not seem to be,

INSERT INTO relaytofrom (relay_ip, record_expires, create_time) VALUES 
('192.168.1', '9999-12-31 23:59:59', NOW());

??
