Topic: Fail2ban blocks entire server after reboot
==== Required information ====

I have iRedMail installed since 3 months and generally it works perfectly.
However, the fail2ban service is enabled by default and it after 20-45 minutes blocks access of every user, and they cannot receive or send any mail.
If I disable fail2ban (service fail2ban stop), then it's all fine again.
On every reboot I have to say "service fail2ban stop" to prevent this from happening.
I am not familiar very much with fail2ban and I haven't changed the default configuration. Can you tell me what i should be looking for?
