I like to be on top of things so I tried configuring a firewall myself using firewall-cmd but somehow I feel like what the iRedMail installation has is more elaborate.
What I have running now is:
[root@email vmail]# firewall-cmd --permanent --list-all
public
target: default
icmp-block-inversion: no
interfaces:

services: dhcpv6-client http https imap imaps pop3 pop3s smtp ssh

Is this enough in your opinion or should I forget about trying to do it myself and use what you install? My knowledge on the subject is limited to what I did so unless it's 1 or 2 small tweaks I wouldn't mind using your settings, if necessary.
Cheers
