Help with sa-learn

I've got my home email server running, with spamassassin's spamc being
called via procmail. So far, so good. Now I'm trying to get bayesian
filtering to work.
I've only got four email accounts on my home server. I get a bunch of
ham (email lists. :) ) and not much spam. My mom gets a bunch of spam,
and not much ham. So, since the bayesian system needs both to learn the
difference, I'd like to set it up so that a root cron job learns from
all of our maildirs at night. Then, when procmail calls spamc, I'd like
for the spamc/spamd to use the bayesian stuff that root learned.
I hope that made sense. LOL
From what I've been able to gather on the internet, I'll know when it's
working because I'll start seeing BAYES_XX tests in the X-Spam-Status
header, which I haven't seen. And I've run a few thousand emails
through this thing now, so I'm beginning to wonder.
Here's the cron job that I've been running at night:
#!/bin/bash
HOME=/root
export HOME
echo `date`
for i in /home/*; do
echo "User: $i"
echo "$i/Maildir/.spam-yes/cur/"
sa-learn --no-rebuild --spam $i/Maildir/.spam-yes/cur/*
echo "$i/Maildir/.spam-yes/new/"
sa-learn --no-rebuild --spam $i/Maildir/.spam-yes/new/*
echo "$i/Maildir/.spam-no/cur/"
sa-learn --no-rebuild --ham $i/Maildir/.spam-no/cur/*
echo "$i/Maildir/.spam-no/new/"
sa-learn --no-rebuild --ham $i/Maildir/.spam-no/new/*
done
sa-learn --rebuild
Here's my /etc/sysconfig/spamassassin:
# Options to spamd
SPAMDOPTIONS="-d -c -a -m5 -H /root"
Here's my /etc/mail/spamassassin:
required_hits 5
rewrite_subject 1
subject_tag [SPAM]
report_safe 0
use_razor2 1
use_bayes 1
Any ideas?
Thanks!
Ben
