We support many systems that use only a daily cron job, bayes-rebuild:

#! /bin/bash
#
# rebuild the bayes database daily
/usr/bin/sa-learn --sync --force-expire -p \
/etc/MailScanner/spam.assassin.prefs.conf

MailScanner.conf settings are:

        Rebuild Bayes Every = 0
        Wait During Bayes Rebuild = no


We very rarely see any problems with the bayes database:
