Please correct me if I am wrong here but the way I see it that: Linux Server is trying to send email to a windows MS Exchange server. IPtables on the Linux Server blocking port 25 (smtp) and that is why your error logs shows that localhost 127.0.0.1 port 25 is not reachable.
I think you should replace the IP in your rule with your linux IP address.
