Hallo,
We are using iRedMail as our school-mail-server. We've discovered a problem. In our school we've got an internet connection via DSL and every 24 hours we get another IP (dynamic IP). We've got 800 pupils and 80 teachers and other staff so it happens quite often that someone tries wrong password which leads us to the problem that for the whole school the mail server isn't reachable.
Is there a way to whitelist the (dynamic) IP in fail2ban?
Thanks in advance!
