Why Dns Error resolving MX for linux.cssit.com ?

For the simple reason that your domain name is cssit.com, what you've used is the FQDN of your server. As you're behind a NAT router you'll need a Split DNS set-up. According to this report, your external DNS records are incorrect as well. You also need your /etc/hosts file to be correct.

There are details in the forums on how to check your DNS settings, please search for them.
