Mailscanner and default Spamassassin fills up /var space

If you are installing Mailscanner and Spamassassin from source or some RPMs it’s been know to use Bayesian statistics engine with it’s database kept forever. This fills up /var/spool/MailScanner/spamassassin folder pretty quickly if you have a moderate load SMTP incoming server. To fix this problem and rebuild Bayesian filters you need to change the following value in /etc/MailScanner/MailScanner.conf file

find the following setting:

Rebuild Bayes Every = 0

and replace it with

Rebuild Bayes Every = 12000

This will rebuild Bayesian spamassassin database/files every 200 minutes. You can of course aim for a higher value if you have enough disk space.
