Yup. It’s so damn annoying hosting email. Do it once to learn, but don’t do it as a permanent solution. It takes so much maintenance to keep it going, if you even do get it working.
What maintenance do you mean? run OS updates and pay the vps bill. that’s true for any self hosted application. which specific maintenance are you referring to?
Setting up the newfangled security thing. TLS, DKIM, DMARC, SPF are the big ones over the years. Finding out you’ve been silently blackisted by a provider and hoping and praying they’ll answer your request to unblock. Managing your own spam filter.
