Do I have to "Use firewall rules provided by iRedmail" inorder for the iRedmail and the firewall security to work properly ?
You don't have to use it, that's why it's an optional step and ask your confirm during installation.

What do you suggest ? If using it is better then how can I enable it ?
If you're not familiar with iptables rules, then it may be a good idea to use default one shipped in iRedMail. But if you're familiar with it, and you know what you need and how to achieve them, just use your own.
