spamassassin

[Joey Prestia]

What is involved with setting up spamassassin for mail filtering. I have 
installed it and started the service spamd but something is missing spam 
   checking is not being done for some reason. Do I have to use spamc 
some how and call it from a .procmailrc or something. I am running RHEL 
5 and sendmail I do not have any sort of procmail setup though it is 
installed in the server. I am not sure how to configure this properly to 
get my mail filtered. Any assistance is appreciated.
