I've now worked through your two sets of tests and rechecked against www.checkDNS.net and appear to have a visible mail server.

You're welcome. (^-^)

Still, I would recommend to read the basic documentation for Postfix in order to get a grip on how Postfix actually works and how you check that everything is working as it should.
This includes the knowledge how postfix restrictions work, the order they are processed, how a normally working system behaves and what logs are normal or alarming.
One very important step is to set up server monitoring, both for hardware and for the Postfix service. Check the disk space regurlarly and send yourself some report about the activity of Postfix. Both can be scripted with little effort for great gain.

It is amazing how much you need to know to administer any mailserver with some degree of competence. But it is sufficient if you know when you are in trouble to scream for help before all hope is lost, and that is where the monitoring steps in.

Last but not least: document your setup and implement a backup. And do that while the knowledge is still fresh in your memory.(^-^)
