netstat returned below which means server is listening on the port 25 and the
IP address is still same 192.168.20.19 from ifconfig -a and still I cannot
connect on port 25. What do I do now?
tcp4 0 0 *.25 *.* LISTEN

If the IP address of the server hasn't changed and Postfix is still
listening on port 25/tcp (check with ipconfig and netstat on the Postfix
server), then something between your client and the Postfix server is
blocking connections to the Postfix server. tcptraceroute may help
narrowing down that something.
