Got it installed, now what?

[Josh Peters <jp...@matric.com>]

Parden me for my ignorance, or maybe this queston doesn't belong here, but 
I've looked at all the documentation and it seems there's an endless amount of 
ways to setup SpamAssassin.  So I'll start from the beginning.  I have a VPS 
FreeBSD server, running Apacahe and Sendmail as my mail service. I also have 
Mysql if it's pertinate to setup? I have a about 80 POP3 mailboxes that are 
running fine. We've been bombarded with SPAM the past few months so I decided 
to start looking for some type of SPAM filtering software and came to 
SpamAssassin.  Yesterday I successfully upgraded my version of Perl in order 
to install SA, and got a clean Make and Install of SA.....

So now what?  I've been trying to figure out how to test this on a single 
mailbox, so I created a directory call /usr/home/<username>/.spamassassin . In 
that I created a file called user_prefs and inserted this code

How do I know everything is running and how do I test this thing?  Again, 
sorry if this isn't the place for a question like this but I'm having issues 
figuring this out.  It's on my server, just need to configure it now.  
Thanks
