Title: Zentyal Blocking Internal Server Notifications?
Post by: circlenaut on October 07, 2017, 03:28:48 am

I have a couple of internal servers that are configured to send me notifications about their status (monit, fail2ban and logcheck). When they face the internet directly I get proper notification, but when I place them behind zentyal I do not. In the firewall module I see all outbound traffic is not blocked. What is going on? what setting do I need to change to allow internal servers to send out postfix emails?
