A much better place to ask would be the spamassassin mailing list.
Send mail to spamassassin-users-subscribe at incubator.apache.org to subscribe

Fundamental misunderstanding of Spamassassin purpose. It is a filter that marks
mail as spam it does not delete or "block it". Usually one uses something like
procmail as a local delivery agent (or similar) that does the actual deleting
or more usually directs it to a separate spam mailbox. Deleting all email 
marked as
spam usually not considered wise because of the possibility of false 
positives.
More common is to mark the lower scoring spam as SPAM and deliver,and only
delete (or maybe archive for some time), the high scoring spam.

Yes read the Spamassassin FAQ and Wiki (and the mailing list archives) and you
will find ways. See http://www.spamassassin.org
