Hi Reindl.
I have a similar script to detect brute force attacs to dovecot sasl
auth sistem, it's very simple to adapt to pop/imap failures log:

Hi
has someone a script which can filter out dictionary attacks
from /var/log/maillog and notify about the source-IPs?
i know about fail2ban and so on, but i would like to have
a mail with the IP address for two reasons and avoid fail2ban
at all because it does not match in the way we maintain firewalls
* add the IP to a distributed "iptables-block.sh" and distribute
it to any server with a comment and timestamp
* write a abuse-mail to the ISP
