Spamassassin not working

[betts at norden1.com]

I have installed Spamaassassin along with amavisd-new to filter spam, but
I don't think it is working. I am getting a bunch of spam and spamassassin
is not tagging it as spam. I have the score set at 3.0. It worked before
on my old box but when I installed it on a new box using the same
procedure I used on the old box it is not working. Anyone have any ideas?

Thanks
