mailu.io is an open source alternative to poste.io and bundles a classing email stack in an easy to use package. But it’s still quite complex under the hood. There is also an upcoming project called maddy( https://github.com/emersion/maddy https://github.com/emersion/maddy) that tries to package everything in a single binary, written in Go. I’m excited about about this and hope that the good folks that are developing it will take it to a usable state.
