> i would not laugh. think it’s impressive and must eat a lot of time It does not. I set up my latest/current email hosting in about 2011. Very minimal work on it since then. There's really nothing to do once it's working. Only work I can think of I've spent on it since 2011 is: regular OS updates (which take basically no time), added SPF and later DKIM support, added Let's Encrypt cert. That's it in ten years.
