As a mailops engineer, there are many times when you may want to spin up a quick install of your MTA to test a theory, or smoke-test a new config before getting it anywhere near your DEV or UAT environments. Or maybe you are a just now investigating the whole KumoMTA thing that people have been talking about and don't want to burn a lot of resources to test it out.
This 2-minute video will walk you through a very quick demo of how you can install KumoMTA for this purpose. The actual time for the full install was just under 5 minutes, but this video is edited so you don't have to waste 3 minutes watching Ubuntu update the OS.
Let us know when we can talk about your future with KumoMTA.
