If you have never done a bayes rebuild, I would recommend you do a manual
rebuild first. (sa-learn --force-expire)
Then the following is what I have for a daily run;

# If you are using the Bayesian statistics engine on a busy server,
# you may well need to force a Bayesian database rebuild and expiry
# at regular intervals. This is measures in seconds.
# 1 day = 86400 seconds.
# To disable this feature set this to 0.
# Note: If you enable this feature, set "bayes_auto_expire 0" in
#       spam.assasssin.prefs.conf which you will find in the same
#       directory as this file.
Rebuild Bayes Every = 86400

# The Bayesian database rebuild and expiry may take a 2 or 3 minutes
# to complete. During this time you can either wait, or simply
# disable SpamAssassin checks until it has completed.
Wait During Bayes Rebuild = yes


I would recommend that you set "wait during bayes rebuild = yes"
so the expiry runs don't get killed by spamassassin accessing the bayes db.
