You are breaking RFC regulations by using an ip address for the MX record instead of a name.

The loopback problem is usually where DNS points to a machine which itself is not accepting mail for the domain.

Fix your DNS

I got the same problem and it's becoming so frustrating for me,my mailserver is behind the firewall and i'm using dyndns to test and it only recognize the IP that's at my firewall.how can i make my other NIC to be recognized by DynDNS.

Can you post the exact error messages from your mail log?
What's the output of
Code:

ifconfig
?

You can try to set smtp_bind_address in your main.cf together with the IP address that you forward port 25 to. (See http://www.postfix.org/postconf.5.html )
