Spamassin - Where is system default user_prefs?

I just set up my mail on DreamHost and have .procmailrc passing mail through spamassassin and then to a PERL program that does a bit more work. I have not used spamassassin before this. I set up a whitelist, have been reading a bit about the various tests. First mail message created my user_prefs file which I can edit. Where is the site file? I would like to see the list of all tests and scores performed for the site.

Thanks, Dale
