dotaz na Bayes filter

[jaroslav.linhart na dev-net.cz]

Dobrý den,
chci se zeptat na Bayes filter.
stáhnul jsem si script 

#!/bin/sh
if [ -e /var/mail/spam ]; then
/usr/bin/sa-learn --spam -p /var/amavisd/.spamassassin/user_prefs \
--mbox /var/mail/spam
rm /var/mail/spam > /dev/null
fi

if [ -e /var/mail/notspam ]; then
/usr/bin/sa-learn --ham -p /var/amavisd/.spamassassin/user_prefs \
--mbox /var/mail/notspam
rm /var/mail/notspam > /dev/null
fi

/usr/bin/sa-learn --rebuild -p /var/amavisd/.spamassassin/user_prefs

a pokud pošlu mail na spam nebo na notspam vypíše tuto hlášku nevíte co by 
to mohlo být?

[root na linux sbin]# /usr/local/sbin/my-sa-learn.sh
