>People shouldn't need to fully understand DKIM, SPF, etc. - they should just be able to click a button, copy&paste generated DNS records, and be up and running.

I oppose this. People should know what they are configuring. This applies to all stuff related to mailservers.

You probably learn more by setting it up the "hard" way (without containers) so that in case of failure you at least have a little insight in how the components work.



There are many more people who want to drive a car, than people who want to learn the minutiae of how it works.

If it breaks, then you get someone else to fix it / get a better product is all they need to know.


Not everything is a car analogy.

But if you want ... it's like having a drivers license.

Or: you only "drive" self-driving cars. In case of emergency you don't know what to do. Perhaps an even better analogy.


I have my own domain, my own bind and my own mail servers. I forward all the mail to google for reading and searching and the main value I get out of it is I actually understand how DNS and SMTP work. Which comes in handy once a quarter at work. I book marked TFA because I never got the newer (!) stuff setup like proper TLS and DKIM. It is very old setup from like 2005 or so and I think is grandfathered into Gmail somehow. At least my newest domain I treated worst than my older ones.
