    I see some strange errors in the fail2ban log (setup according https://www.howtoforge.com/tutorial...n-8-jessie-apache-bind-dovecot-ispconfig-3/2/)

    So I disabled al filters and enabled them one by one to find the problem.

    When enable "dovecot-pop3imap" I get this error
    Code:
    2015-08-21 00:28:19,661 fail2ban.filter [34590]: WARNING Unable to find a corresponding IP address for ::1: [Errno -9] Address family for hostname not supported
    
    This is the code from the filter:
    Code:
    [Definition]
    failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P<host>\S*),.*
    ignoreregex =
    
    what could be the problem?

    thats a ipv6 ip and fail2ban does not support ipv6 yet.

    Like I said, fail2ban does not support ipv6 yet. So that's not related to the installation of fail2ban.
