Scoring questions

[Computer Bob]

I modified the following SA local.cf items:
---------------------------------------------------------------------------------------------------
#   Add *****SPAM***** to the Subject header of spam e-mails
#
  rewrite_header Subject *****SPAM*****   <---- Uncommented

#   Use Bayesian classifier (default: 1)
#
  use_bayes 1       <---- Uncommented

#   Bayesian classifier auto-learning (default: 1)
#
  bayes_auto_learn 1            <---- Uncommented

#   Set headers which may provide inappropriate cues to the Bayesian
#   classifier
#
# bayes_ignore_header X-Bogosity
# bayes_ignore_header X-Spam-Flag
# bayes_ignore_header X-Spam-Status
---------------------------------------------------------------------------------------------------
I added the following:
---------------------------------------------------------------------------------------------------
#dcc
use_dcc 1
dcc_path /usr/local/bin/dccproc

#pyzor
use_pyzor 1
pyzor_path /usr/bin/pyzor

#razor
use_razor2 1
razor_config /etc/razor/razor-agent.conf
--------------------------------------------------------------------------------------------------
I also copied the current KAM.cf to the /etc/spamassassin folder.
Any further suggestions ?
