Odd local.cf problem

[Munroe <ms...@gmail.com>]

I am running SpamAssassin 3.1.4 on a windows mail server, the local.cf
file is in /perl/site/etc/mail/spamassassin

This is what it looks like:

# This is the right place to customize your installation of SpamAssassin.

# See 'perldoc Mail::SpamAssassin::Conf' for details of what can be

# Only a small subset of options are listed below

###########################################################################

#   Add *****SPAM***** to the Subject header of spam e-mails

rewrite_header Subject [SPAM]


#   Save spam messages as a message/rfc822 MIME attachment instead of
#   modifying the original message (0: off, 2: use text/plain instead)

report_safe 1


#   Set which networks or hosts are considered 'trusted' by your mail
#   server (i.e. not spammers)

trusted_networks 205.158.155.180
trusted_networks 205.158.155.52

#
# lock_method flock


#   Set the threshold at which a message is considered spam (default: 5.0)
#
required_score 5.0


#   Use Bayesian classifier (default: 1)
#
# use_bayes 1


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


#   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

As you can see I have added about 6 mailservers as "trusted" and
disabled rbl checking or so I thought.  messages from those mail
servers (the trusted ones) are still getting bounced for being on a
black list.  Since spamassassin is running as an exe and is envoked
everytime mail is delivered it is loading the new config, I have
confirmed that by changing the required_score and I see that change
immediatly.  For some reason Ican't whitelist or disable rbl checking.
 Am I forgetting something or doing some thing wrong?
