Go to
this page and install the webmin package, when it's installed go to the login page and then to the Servers/BIND DNS server page. In there you should see the configuration of your DNS server and defined Zones, go to your Zone then 'edit the records file' and you'll see the DNS records for your Zone. You just need to add the record I gave you earlier save the change and then restart your DNS server and you should see the correct record when you run the dig command again. Who actually set the DNS records for you on this server?

It's not a good idea to have a mail server (or any server) exposed to the internet without a firewall active.
