hello I have installed fail2ban. I started to receive this error. Code: --------------------- fail2ban-messages Begin ------------------------ **Unmatched Entries** 2009-02-11 02:13:21,694 fail2ban.comm : WARNING Invalid command: ['set', 'courierpop3', 'failregex', 'courierpop3login: LOGIN FAILED.*ip=\\[.*:<HOST>\\]'] ---------------------- fail2ban-messages End -------------------------
Can you post your courierpop3 ruleset? Do you have failed login messages from Courier in your mail log? If so, can you post them here?
