Compose Mailserver

Sets of scripts to generate mailserver configuration and send it to a Linux machine.

Requirement

To use this software you will need to be on a Linux-like Operating System and have the following software installed:

• Bash
• Coreutils
• GCC Toolchain
• Make
• Makeself (if your enable Makeself output)
• OpenSSL (if you enable SSL support)

Currently, all test are done on Debian 13 .. Support for other distros will come.

Usage

Use pre-existing configuration

Pre-existing configuration exist in configs/, to use them run:

$ make <defconfig_file>
$ make menuconfig  # You still have to customize at least General setup (domain & ip)
$ make

List of defconfigs:

• postfix_dovecot_minimal_defconfig: A minimal postfix / dovecot server with no web frontend using PAM auth

From scratch

You can also configure your own setup by skipping the defconfig part:

$ make menuconfig
$ make

Serverside installation

Once you have configured and generated your artifacts, you can send them to your server.

List of artifacts:

• tarball: A simple tarball with your configuration.

• makeself: A self installer which can be executed on your server (with root perm) to install everything. Once done, just reboot and you have a fully fonctional mailserver.
