Topic: iRedmail and fail2ban

==== Required information ====
- iRedMail version: 0.8.7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):  LDAP
- Linux/BSD distribution name and version: Ubuntu 12.04.3 LTS 64-bit
- Related log if you're reporting an issue:
====

fail2ban drops our public IP. How to whitelist a specific IP address so it wont block it in iptables? I already added the ip /32 in jail.conf but still our public ip was blocked.

Re: iRedmail and fail2ban

Two ways:

1) Fail2ban invokes iptables to block client IP address if there're too many password failures in period. So you have to avoid many password failures in a short period.
2) If your public IP is a static IP address, whitelist it in Fail2ban config file /etc/fail2ban/jail.local.

Hi Zhang,

Glad to hear from you. I see I added our public static IP in jail.conf ignoreip. So I have to do the same with jail.local ignoreip if thats the case then.

Will do. Thanks!

Re: iRedmail and fail2ban

jail.conf may be override during package update, you'd better add it in jail.local.

Thanks Zhang. iRedmail is now in production and I'm gonna observe how it goes. Hope it does not block it again.

Hi Zhang,

you may now close this case. It's been 3 days and our static ip address is not anymore blocked by fail2ban. Thanks!

PS I've also created a post in success stories smile Thanks!
