Hi,
I am a fail2ban user and i am very interested to have an autosent mail to the ip provider of the brute force ip address.
Do you know if it is possible with fail2ban or if we have to rewrite action in fail2ban ?.

Maybe a brute force attack, try to install a HIDS like:
APF/BFD: http://www.rfxn.com/projects/advanced-policy-firewall/
http://www.rfxn.com/projects/brute-force-detection/
Fail2ban: http://www.fail2ban.org/
Fail2ban is available in EPEL repos.
