I’ve hosted my own Mailserver in various configurations since more than 6 years now. Since then I’ve taken multiple breaks from hosting it myself and explored other solutions for hosting emails with your own domain names. Because my own Mailserver has lately problems (downtimes) I wanna explore other possibilities of hosting my email addresses. So let’s take a look… Self-hosting (VPS, Tools like Mailcow, Mailu, etc) You simply setup a Mailserver with software like Mailcow, Mailu or Mail-in-a-Box on a virtual Server and manage it yourself.
