there is no logfile nor attachment

Re: fail2ban Banned IP Addresses often

I upload again the log file. Please kindly check if available. Mail users said they didn't try wrong password and it's happening everyday. And i don't wanna stop fail2ban services and don't wanna ignore this ips in fail2ban. It's happening minimum 5 times per day.

most of jail type is roundcube. I think also  it is happening because of wrong credentials. but it's happening day by day. How can i set up to ban only that wrong user. Now this is banned the public ip and the whole office staffs can't use mail service at this time

Re: fail2ban Banned IP Addresses often

look exactly what client uses wrong credentials and then teach him a lesson of "how not to fuck with the IT"

for me, it looks like this is done on purpose
