spamassassin config help

[AN]

I just setup a new mailserver on 8-stable using sendmail with Spamassassin 
and ClamAv.  Spam is being identified correctly, but it is being 
delivered to users inbox.  Would someone please suggest some good 
documentation to configure mail marked as spam to a different directory. 
Are there any scripts or tools to configure Spamassassin?  Where is the 
spamassassin config file?  Thanks in advance for any help.
