Topic: Client host rejected

- iRedMail version (check /etc/iredmail-release): 0.9.6
- Linux/BSD distribution name and version: Debian Jessie
- Store mail accounts in which backend (MySQL): Mariadb
- Web server (Apache or Nginx):Apache
- Manage mail accounts with iRedAdmin-Pro? No
- Related log if you're reporting an issue: Diagnostic-Code: smtp; 554 5.7.1 <unknown[x.x.x.x]>: Client host rejected:
====

I'm trying to relay mail to an IRedMail server. I installed postfix on two servers that will send email notifications to the iredmail server but the iRedMail server rejects mail from these two hosts. I added ip addresses of these to main.cf

mynetworks = 127.0.0.1, x.x.x.x , x.x.x.x

I have also added the ip addresses on /opt/iredapd/settings.py
# My Networks
MYNETWORKS = ['x.x.x.x' , 'x.x.x.x']

I tried relaying to a Windows based mail server called HMail Server it worked but I don't wanna use Windows in my infrastructure.
