Eric,
I am currently using the qtp-clean-spam script on my server. It runs
once per hour. During the run is learns and then deletes anything older
than five days (the number of days is adjustable).
I will look into your adjusted rules.
Thanks to everyone for your suggestions and help. I would like to some
day see a nice write up on the wiki about tweaking spamassassin to
increase spam fighting effectiveness.
Thanks,
Scott

Good that your users are IMAP. There's a qtp-clean-spam script in QTP
which runs sa-learn against users spam directories. I'm not positive
how that works, as I use a little different method.
Anyone here using qtp-clean-spam script?
Once you have a bayes database developed (takes time), you should
adjust your scoring for bayes to weigh more heavily. Here's what I'm
presently using in local.cf (standard scores in comments):
# adjusting these scores gives bayes more weight
# commented values are the defaults
# score BAYES_00 0 0 -2.312 -2.599
# score BAYES_05 0 0 -1.110 -1.110

# score BAYES_40 0 0 -0.185 -0.185
