Mail-in-a-Box is a free and open-source program for mail server hosting developed by Joshua Tauberer. [1] [2] The software's goal is to enable any user to turn a cloud system into a mail server in a few hours. [3] The tool enables developers to host mail for multiple users and multiple domain names. [4] [5]

The default configuration provides a spam detection system, monitoring, reporting and backup mechanisms. [6] It can also set up and automatically renew a Let's Encrypt certificate, as well as configuring the detailed DNS configurations needed to ensure that a mail server's IP address is trusted by other servers, and less likely to be blacklisted. [6] [7] Its support for IMAP/SMTP facilitates synchronizing across devices. [7]

First developed in 2013 by Tauberer, the tool is written in Python and Bash. The project supports Ubuntu LTS. [8] [9]

It has been recommended by the notable Hackaday and MakeTechEasier. [10] [11]
