No bayesian for me?

[Mauricio Tavares]

	Ok, I thought I knew how to setup bayesian under mailscanner.  I went 
to spam.assassin.prefs.conf and added

# Bayesian filter
use_bayes 1
use_bayes_rules 1
bayes_path /var/spool/MailScanner/bayes/bayes
bayes_auto_learn 1
bayes_file_mode 0640
bayes_auto_learn_threshold_nonspam 0.1
bayes_auto_learn_threshold_spam 12.0
bayes_ignore_header X-monetra-com-MailScanner
bayes_ignore_header X-monetra-com-MailScanner-SpamCheck
bayes_ignore_header X-monetra-com-MailScanner-SpamScore
bayes_ignore_header X-monetra-com-MailScanner-Information

lock_method flock
use_auto_whitelist 0

But I am getting emails whose header seem to indicate the bayesian 
filter is not present:

X-MailScanner: Found to be clean
X-MailScanner-SpamCheck: not spam, SpamAssassin (not cached, score=4.464,
         required 4.7, HTML_MESSAGE 0.90, INVALID_DATE 0.50,
         MIME_HTML_MOSTLY 0.00, MIME_QP_LONG_LINE 1.82, MISSING_MIMEOLE 
0.00,
         MPART_ALT_DIFF 1.14, RDNS_DYNAMIC 0.10)
X-MailScanner-SpamScore: ****
X-MailScanner-Envelope-From: promolx1 at tutopia.com
Subject: -Soluciones para tiempo y asistencia-
X-Spam-Status: No

Anything I could be missing? I believe there is a way to ask mailscanner 
if it has bayesian but I can't remember it.
