    Hello, i have followed the tut
    and have completed all steps by the book (triple checked this one).

    The squirrelmail_access_log has been created and there are 4 failed tries like:
    04/18/2012 09:46:23 [LOGIN_ERROR] [email protected] (localhost) from Unknown user or password incorrect.

    After i use the fail2ban-regex /var/lib/squirrelmail/prefs/squirrelmail_access_log /etc/fail2ban/filter.d/squirrelmail.conf

    i get the Following error:

    Running tests

    Use regex file : /etc/fail2ban/filter.d/squirrelmail.conf
    Use log file : /var/lib/squirrelmail/prefs/squirrelmail_access_log

    As you can see my python version is 2.4, the Fail2ban version is 0.8.4-29.el5(epel) though i have tried this on the 8.2 with the same error( i did upgrade to 8.4 since two days now).

    I have also followed the instructions on this topic (exacly the same problem but python 2.6)
    without success...any one has this problem solved?
    I admit giving up on this one although a system is as strong as your weekest link :S

    Can you post your /etc/fail2ban/filter.d/squirrelmail.conf file?

    This is it:

    # Fail2Ban configuration file
    # Author: Bill Landry ((email_protected))
    # $Revision: 510 $


    # Option: failregex
    # Notes.: regex to match the password failures messages in the logfile. The
    # host must be matched by a group named "host". The tag "" can
    # be used for standard IP/hostname matching and is only an alias for
    # (?:::f{4,6}:)?(?P\S+)
    # Values: TEXT

    failregex = \[LOGIN_ERROR\].*from <HOST>: Unknown user or password incorrect

    # Option: ignoreregex
    # Notes.: regex to ignore. If this regex matches, the line is ignored.
    # Values: TEXT

    ignoreregex =

    Looks ok. Did you save the file with Unix linebreaks or maybe with Windows linebreaks?

    The file is created from linux vi editor how could this be in win format?

    Then it uses Unix linebreaks which is ok. Unfortunately I have no idea what's wrong... :(

    I did a :set fileformat=unix just to be sure...

    Unfortunately i have goggled everything i could think of with no result...
    I hope someone sees this topic and perhaps make a suggestion that will help.
    Thanks for your time falko!
