sa-learn - Munin plugin to monitor spamassasin bayes database size
Any server running spamassassin
This plugin assumes your Spamassassin database is in /var/lib/MailScanner. If it's elsewhere (or you want to use a different database) you will need a configuration such as:
[sa-learn] env.BayesDir /path/to/bayes/directory/ user mail
(where 'user mail' refers to a user that can read the database).
