Setup your own personal mail server

Have you ever wanted to quickly setup your own dedicated mail server? Setting up a personal email server is very easy to do. We’ll show you everything you need to quickly deploy your own mail server on a ServerMania Hybrid, Cloud, or Dedicated Server using the popular Mail In A Box platform.
