As I got further into my thirties, I became much more aware of the concept of opportunity cost: by deciding to do one thing, I'm by definition deciding to not do others. Running my own mail server is one task that has not made the cut for being more worthwhile than other priorities in my life.

Sad to see all the negativism. To anyone considering it, just run your own email infrastructure and don't let the naysayers put you down. Email is far too critical to let any megacorporation own you on it.

I spend approximately no time at all in maintaining my email infrastructure which I set up around ~10 years ago.

Of all the things I self-host and self-manage, my email server and related parts is the one which requires the least attention and ongoing work, by far. Set up postfix, it'll take some work initially, then it'll chug along forever.
