why run all of those cron jobs separately?

# cat spam
#!/bin/sh
LEARN="/usr/bin/sa-learn"
HOME_FOLDER="/home/users"
MAIL="mail"
USERS="/root/scripts/users-spam-check"
SHELL="/bin/sh"
SPAM="SPAM-learn"
HAM="SPAM-not"

for i in `cat $USERS`; \
do su - $i -s $SHELL -c "$LEARN --mbox --spam
$HOME_FOLDER/$i/$MAIL/$SPAM"; \
su - $i -s $SHELL -c "$LEARN --mbox --ham $HOME_FOLDER/$i/$MAIL/$HAM"; \
cat /dev/null > $HOME_FOLDER/$i/$MAIL/$SPAM; \
cat /dev/null > $HOME_FOLDER/$i/$MAIL/$HAM; \
done
