Its quite safe to run a cron for clean up, mailscanner includes it own cron
script to do that. As for mailwatch, you won't be able to view the message
content of quarantined mails that don't exist anymore (though the rest being
in the mysql db will work as usual).

You'll need the following 2 actions.

1. MailScanner has it's own cron for quarantine deletion, change
$days_to_keep to 14.
Check /etc/cron.daily/clean.quarantine OR
/opt/Mailscanner/bin/cron/clean.quarantine.cron

2. Run another script to trim the mailwatch database
minute hour * * * /path/to/mysql -u mailwatch_user
 --password=mailwatch_password < /path/to/mailwatch_mysql_mailtenance.sql

Content of /path/to/mailwatch_mysql_mailtenance.sql:
delete from maillog where timestamp < date_sub(curdate(), interval 14 day);
optimize table maillog;

Hope that helps,
