Amavisd not identfying spam properly

[Cracklefish]

I thought the .Spam folder was made when I set up a custom rule to move tagged emails there but it might have been Squirrelmail. I am now so confused with this setup. I have been hacking at it for weeks. I have just discovered the quarantine directory with more than 35,000 files in it which I have deleted. I have set up a cron job to delete aged stuff. What I'm trying to achieve is giving each mail domain the option of tagging or deleteing spam but I don't seem to have found answer yet. My amavisd.conf is posted earlier in this thread. Any help will be gratefully received.
