Mail-in-a-Box
Mail-in-a-Box is a free, Open Source software for mail server hosting developed by Joshua Tauberer. The software's goal is to enable any user to turn a fresh cloud system into a Mail server in few hours. The tool enables developers to host mail for multiple users and multiple domain names while controlling the entire process top to bottom. 

The default configuration of the software provides a spam detection system, monitoring, reporting and backup mechanisms. It can also set up and automatically renew a Let's Encrypt certificate for your email domains, as well as configuring the detailed DNS configurations needed to ensure your mail server's IP address is trusted by other servers, and less likely to be blacklisted.

First developed in 2013 by Tauberer, the tool is written in Python and the current version runs on Ubuntu Server 18.04.
