Thank you so much for the detailed reply. I'm fairly new to programming, development, Linux, the command line, etc etc, and so am always on the lookout to learn something new. My day job is web development, but I'm looking for something that I really want to dive deep into. Email seems to be a whole universe of its own! From what you've said, maybe I'll try it once to learn a bit more someday, but for now I'll let sleeping dogs lie and keep G Suite as my custom domain email host. Thanks again!
