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

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 )
Hi Thanks i'l read through the document and see i can have this time. i'll keep everybody posted if it works for me.
