You'll never know if internal messages are ever spam or not; your script is the
best way to
a) poison your bayes database through unsupervised user interaction and
b) put unneccessary load on your server.
Bayes is just one of the many factors Spamassassin takes into account for
computing the spam score.
Usually you would first train your Spamassassin on a good ham and spam corpus with enough messages that after that
Spamassassin's autolearn feature is enabled - I guess the threshold is 200 messages for each category before autolearn will
start to work.
After that you normally only would train Spamassassin on its errors from time to time, nothing more, nothing less, maybe once
a week or though because a well trained and maintained Spamassassin behaves well enough and doesn't need more maintenance than
this. You can even make it more comfortable by using stuff like the antispam plugin from Dovecot if you want to.
BTW, this line in the script is a security nightmare:
mysql -N -u root –p<mypwd> -D mailscanner
This means that any user on the machine is able to read the root password with the means of using ps, e.g. "ps max | less",
when its running. Not good at all.
Set up /root/.my.cnf:
[client]
user=root
password=SuperDuperSecret
Then use the HOME trick (from my crontab):
HOME=/root mysqldump --opt --order-by-primary -f -R -r
/home/webmaster/mysql.backups/pkg_phpmyadmin.sql pkg_phpmyadmin
