Install Mail-in-a-Box on Ubuntu 16.04 LTS

In this tutorial we will show you how to install and configuration Mail-in-a-Box on Ubuntu 16.04. For those of you who didn’t know, Mailinabox is a free and open source software that deploys a complete full stack email solution with a well managed server control panel in few simple minutes. Deploying our own well managed email server is pretty easy with Mailinabox now.

Mailinabox has the ability to host multiple domains email and provides webmail, contacts, calendar synchronization and IMAP/SMTP server setting so that we can access our emails with mobile devices and desktop mailing clients.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS.
