Hello Atıf CEYLAN, Am 2012-08-14 14:51:17, hacktest Du folgendes herunter: > you can use fail2ban program or block the ip by iptables manually. > I'm suggestion fail2ban. it's a login attempt counter. And what do you suggest to with customers which use my storage servers as there mailstore and fetch all uses by fetchmail? Now I am puzzeling arround, because fail2ban block even normal Logins if they happen to fast... Exactly: An enterprise use the M$ Exchange server internaly, but use my server as thre mailserver and it has 20-50 users to fetch (fetchmail). The Exchange server does this all 10 minutes sequentialy but is very fast as my internet connectivity (1 GE) and check without any problems 20 accounts in less then 15 seconds. BANNED! :-S Not very funny!
