I already have SpamAssassin installed, but it's not enought.
With this small script I caught 8 bad guys in 15 minutes. The script is called
by crontab every 5 minutes and every 23:59 (11:59 pm) I run the following
command to take them out of the punishment:
echo -n > /var/MailRoot/spammers.tab
Here goes the script:
============================
#!/bin/sh
spammer() {
if [ $2 -gt 30 ]; then
if [ ! "`grep \"^$1\/24\$\" /var/MailRoot/spammers.tab`" ]; then
echo "$1/24" >> /var/MailRoot/spammers.tab
fi
fi
}
tail -n 1000 /var/MailRoot/logs/smtp-`date +%Y%m%d`0000 | \
sed 's/"//g' | cut -f3,4 | sort > /tmp/$$
while read ip datetime ; do
if [ "$ip" = "$lip" ]; then
let n=$n+1
else
if [ "$lip" ]; then
spammer $lip $n
fi
n=1
lip=$ip
fi
done < /tmp/$$
rm -f /tmp/$$
if [ "$ip" ]; then
spammer $ip $n
fi
==========================
Just it!
