[Dovecot] Fail2ban and logging

Hello,

Dovecot is logging authentication failures this way:

Jul 12 18:07:19 vps0 dovecot: imap-login: Disconnected (auth failed, 22 attempts in 172 secs): user=<info>, method=PLAIN, rip=82.95.148.152, lip=1.2.3.4, TLS, session=<QylMqlLhVwBSX5SY>

Fail2ban is trying to catch them with this regex:

failregex = .*(?:pop3-login|imap-login):.*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed).*rip=(?P<host>\S*),.*

This way fail2ban is counting 22 attempts as 1 attempt...

I expect I need to change something on the logging, so that every attempt is seperate logged. But I don't know how.

Is here somebody who knows how to get fail2ban correct working?

No help on this on the wiki's: http://wiki1.dovecot.org/HowTo/Fail2Ban http://wiki1.dovecot.org/Logging http://www.fail2ban.org/wiki/index.php/Dovecot
