[K12OSN] Spam help...

[Shawn Powers]

Would someone that is successful using spamassassin to filter most  
spam be willing to contact me offlist for some help?

I've tweaked spamassassin, added rulesets (rulesdujour), lowered the  
required_hits to 4.0, and I'm still having 2nd grade girls getting  
junkmail regarding male pills...

I have angry parents, angry teachers -- and I understand why!  (Yes,  
I know spam is a fact of life on the internet, but I'm doing  
something wrong I think, because it's really ridiculous the amount  
that is getting through)

I'm using:

K12LTSP 4.2.1 as my mail server
Spamassassin 3.0.4 (latest in the updates from k12linux)
sendmail
/etc/procmailrc (yes, I know not the most efficient, but I haven't  
had time to get a milter to work)
RulesDuJour -- to get a ton of rules (I added this on Friday, didn't  
help much)

I have not set up bayesian stuff -- because I believe that I'd have  
to get thousands of spam and ham to make it work -- and I don't have  
the resources to do that (resources = time).  Is that my only chance  
to filter all the crap that's coming in?  Should I invest in a 3rd  
party solution?

Thanks for any insight,
-Shawn
