Topic: Info: roundcube-plugin rcguard - extend fail2ban with captcha

maybe somebody might be interested in this plugin for roundcube as fail2ban might not always be the proper solution: rcguard

imagine you have a customer that connects to your server having 10 users behind his IP

whitelist in fail2ban or life with failed logins?

if you set fail2ban to drop after 20 failed logins you might love this as your customer might not get blocked when all users try to connect in the morning wink

This plugin logs failed login attempts and requires users to go through
a reCAPTCHA verification process when the number of failed attempts go
too high. This provides protection against automated attacks.

Failed attempts are logged by IP and stored within MySQL. IPs are also
released after a certain amount of time.
