I host my email, just not at home but on a rented server.
Here I documented it all https://wiki.gardiol.org/4-e-mail-hosting
It works, its been working for decades now. Never had significant issues…
Email is quite resilient. Servers keep trying to send again and again messages for hours before they give up… So a backup server is not even really required.













Cool!
So it was 1.0.0 after 0.9.0 after all…
