I personally rent a small VPS (At https://www.netcup.eu/, German hoster) with Ubuntu server and use Mailcow (as Docker container) with it.
Setting this up was relatively quick (2-3 hours maybe?), but you really need to know what you’re doing. Like getting started with the container is easy, but you also have to set up DNS for your server, reverse DNS and several things for your email server to look legit (DKIM, certificates, spf DNS entry, …).
After the setup it runs well, though there are still things you’ll have to be careful about. Like making sure that your certificate (usually LetsEncrypt, it’s free) gets switched out regularly in the container (with a post-certificate-renewal hook usually).
Overall, quite a headache if you don’t like to mess around with things.
And even worse if you fully rely on that mail server for important things. I still don’t use my own one for work, banking, taxes and so on, just too risky.
