Adi,

thanks, what I get is:

# /usr/bin/fail2ban-regex /var/log/dovecot.log
/etc/fail2ban/filter.d/dovecot.conf

Running tests
=============

Use   failregex filter file : dovecot, basedir: /etc/fail2ban
Use      datepattern : Default Detectors
Use         log file : /var/log/dovecot.log
Use         encoding : UTF-8
