Добрый день.

Я не силен в настройках сервера и все, что с этим связанно. Заранее прошу не пинать.
Fil2ban отлично отрабатывал все ip, но вот уже дней пять с одного ip ломятся в exim, хотя этот ip есть в iptables. Наткнулся на такое решение https://serverfault.com/questions/60...already-banned но как то не рискнул. Подскажите, в чем может быть дело?
