It is also worth mentioning that it records the IP address of every failed login attempt so it is easy to integrate with your own solutions such as htaccess deny directive.
I am using mainly Polish language so it is obvious that fairly quickly I encountered a problem with national characters in the subject line. Problem is not fixed in Debian packages (using Debian Wheezy x86_64 and Kolab Systems – Public Repositories) but luckily it is very easy to fix.
