Too much spam

[Julio Cesar Covolato]

Hi.

How can I fine tune spamassassin to block more spam?

I instaled iRedMail-0.6.1 in an ubuntu 10.04, amavisd-new-2.6.5 
(20110407), dell Xeon 4 core whith sas disks

The sistem is well working , very fast, but too much spam!
Today i installed pyzor and razor and no mutch diference in amount of 
spam droped in clients mailbox!!!

Working whith +-80.000 messages recived and +-30.000 messages sent by day.

Any hints?

Thanks in advance,
