You also need a proper SSL certificate I think. I looked into it. It seemed more effort than just typing in the details. There's an option to enable it within WHM. Not sure whether plesk has it as well.
Hi cowasaki,,
What exactly are you trying to do?
Are you wanted to set up your own mail server? if So, what Os are you using?
Are you behind a proxy/firewall or an online hosted Vps?

There is creating the DNS record (which you have done) and then there is the XML file with all the settings in.
The DNS points to this file which the client uses to populate the settings.
Here is a quick guide for Linux
