Topic: ports to be blocked.

I installed and successfully running iredmail open source version with postfixadmin.
In Iptables file, you have oepned 80,443,25,465,110,995,143,993,587,465,22 port to all.
Now i would like to host this iredmail server exteranlly to some of my friends for testing.
For this , i need to install the mail server in DMZ zone of firewall.
What question what are changes needed in iptables file
a).if i allow only http access,SMTP access, POP3 access and IMAP access to external users.
b). https access only to internal network so that only internal users can operate postfixadmin,phpmyadmin etc.

Why not just open and forward these ports on your firewall?  Would be much easier.
