Spamassassin seems to be in an incomplete loop

[Kizito Thomas]

Dear Good people,
I am a newbie on Mailscanner so any pointer is well appreciated before
hand.
I have spent the recent days trying to get Mailscanner, Clamav and
Spamassassin work on a Ubuntu 10.04.3 LTS running postfix 2.7.0 but
something is keeping on stopping it from working.
The MTA is working fine with out Mailscanner (when I comment out
header_checks = regexp:/etc/postfix/header_checks
from /etc/postfix/main.cf, mails get delivered).
At first I installed and configured mailscanner according to
http://www.linuxmail.info/mailscanner-postfix-clamav-spamassassin-howto-ubuntu-10-04/  but I couldn't have mails leaving the mail queue. When I check '/var/log/mail.log', I find a serie of repetitive logs, making me think there is some sort of incomplete loop spamassassin enters. (the logs are at the end of the mail)
When I tried to read about this, I found Mohammed Alli saying that the
Mailscanner provided by Ubuntu is broken.
http://www.mailscanner.info/ubuntu.html 
But even when I followed the step up there, there was no change.
I have tried to read the Mailscanner_manual_version 1.0.1 which talks
about auto_whitelist under /etc/MailScanner/spam.assassin.prefs.conf but
it doesn't make any difference setting 'use_auto_whitelist' to 0 or 1.
More reading dropped me to
http://wiki.apache.org/spamassassin/AutoWhitelist which talks about
loadplugin Mail::SpamAssassain::Plugin::AWL
in  /etc/mail/spamassassin/v310.pre but i found it commented out, even
uncommenting it didn't change a thing.
I hope I have provided enough information on my problem for help.
Thank you in advance.
