Re: how to save iptables rules?

Why are you working with iptables? it was dropped years and years ago.

It was replaced with firewalld, so config files are in /etc/firewalld/ 
and default iredmail rules are in /etc/firewalld/zones/iredmail.xml

Re: how to save iptables rules?

You can use firewalld, it uses iptables at the backend. If you want to use iptables on its own CentOS 7, first mask firewalld:
# systemctl stop firewalld
# systemctl mask firewalld

And install iptables as a service:

# yum install iptables-services
# yum enable iptables

You can then edit /etc/sysconfig/iptables (and consequently, use 'iptables-save > /etc/sysconfig/iptables' to save your current setup.  Whenever you make changes to the files, you have to:

# systemctl restart iptables
