Answer : how to open port 25

Change inet_interface = 192.168.1.1 and restart the service.
then execute
netstat -an |grep :25 |grep tcp
and see the results if it comes up with 192.168.1.1 or same 127.0.0.1
This way we can make sure we are modifying the exact file and service is actually using that file and restarted.
