Can’t a corporation just enter the space whenever they want to? Can’t they start or even buy out larger instances? Even if Lemmy does take off, wouldn’t this inevitably happen anyway if the space gets popular enough?

    You need a fixed, non-residential IP address. You need a domain name with SPF. You need to set up DKIM. And you need to set up DMARC.

    In theory, you only need DMARC, but some old email software somewhere might not support it.

    And then you can use services like https://www.mail-tester.com/ to check if everything is set up correctly.
