Mail-in-a-Box helps individuals take back control of their email by defining a one-click, easy-to-deploy SMTP+everything else server: a mail server in a box.

Mail-in-a-Box turns a fresh Ubuntu 18.04 LTS 64-bit machine into a working mail server by installing and configuring various components.
It is a one-click email appliance. There are no user-configurable setup options. It "just works."
The components installed are:
It also includes system management tools:
It also supports static website hosting since the box is serving HTTPS anyway. (To serve a website for your domains elsewhere, just add a custom DNS "A" record in you Mail-in-a-Box's control panel to point domains to another server.)
For more information on how Mail-in-a-Box handles your privacy, see the security details page.
See the setup guide for detailed, user-friendly instructions.
For experts, start with a completely fresh (really, I mean it) Ubuntu 18.04 LTS 64-bit machine. On the machine...
Clone this repository and checkout the tag corresponding to the most recent release:
$ git clone https://github.com/mail-in-a-box/mailinabox $ cd mailinabox $ git checkout v0.54
Begin the installation.
$ sudo setup/start.sh
The installation will install, uninstall, and configure packages to turn the machine into a working, good mail server.

Post your question on the discussion forum instead, where maintainers and Mail-in-a-Box users may be able to help you.
Note that while we want everything to "just work," we can't control the rest of the Internet. Other mail services might block or spam-filter email sent from your Mail-in-a-Box. This is a challenge faced by everyone who runs their own mail server, with or without Mail-in-a-Box. See our discussion forum for tips about that.
