okay, I've updated ISPconfig now, to get a clean system status. The bayes filter are working again.
Now I would like to enable sa-learn again. In my first attempt, it lead to all my troubles with spamassassin and bayes, so I would like to ask for the best way to do this. The idea is to have two users, who are able to copy spam and ham mail into dedicated mailfolders. Than there should be a cron job, which calls sa-learn and deletes the messages afterwards.
Is there anything, I should take into account? User rights, whatever, ...? The scripts I've previously used are invoked by root and look like this:
$SA_LEARN_CMD --spam -C $SA_CONF_DIR $SPAM_DIR
$SA_LEARN_CMD --ham -C $SA_CONF_DIR $HAM_DIR
for i in `find $SPAM_DIR* -mmin +75`; do
for i in `find $HAM_DIR* -mmin +75`; do
