Topic: Check where the email lock came from.

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====

- Linux/BSD distribution name and version: Ubuntu
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MariaDB

The email server is blocking some Iredmail users from being attempted. I want to know how to identify in the server logs, which email is performing the incorrect login attempts so I can fix the problem. Thank you.

Fail2ban program will scan log files and ban bad clients. You can check /var/log/syslog to check why Fail2ban banned the clients.
