How to enable in iptables outgoing traffic from selected domain

I'm having problem with iptables who block the outgoing email from my php script. It will be working well if I stop the iptables. stopping the iptables is unsafe for the server and not the right way to do. what I wanted to do is to allow the selected domain to bypass iptables and send out the email. Anybody can help on this?

below is the error message.
