<h1 id="welcome-to-the-documentation-for-docker-mailserver"><a class="toclink" href="#welcome-to-the-documentation-for-docker-mailserver">Welcome to the Documentation for <code>docker-mailserver</code>!</a></h1>
<div class="admonition info">
<p class="admonition-title">This Documentation is Versioned</p>
<p><strong>Make sure</strong> to select the correct version of this documentation! It should match the version of the image you are using. The default version corresponds to the <code>:latest</code> image tag - <a href="usage/#tagging-convention">the most recent stable release</a>.</p>
</div>
<p>This documentation provides you not only with the basic setup and configuration of DMS but also with advanced configuration, elaborate usage scenarios, detailed examples, hints and more.</p>
<h2 id="about"><a class="toclink" href="#about">About</a></h2>
<p><code>docker-mailserver</code>, or DMS for short, is a production-ready fullstack but simple mail server (SMTP, IMAP, LDAP, Anti-spam, Anti-virus, etc.). It employs only configuration files, no SQL database. The image is focused around the slogan "Keep it simple and versioned".</p>
<h2 id="contents"><a class="toclink" href="#contents">Contents</a></h2>
<h3 id="getting-started"><a class="toclink" href="#getting-started">Getting Started</a></h3>
<p>If you're completely new to mail servers or you want to read up on them, check out our <a href="introduction/"><em>Introduction</em> page</a>. If you're new to DMS as a mail server appliance, make sure to read the <a href="usage/"><em>Usage</em> chapter</a> first. If you want to look at examples for Docker Compose, we have an <a href="examples/tutorials/basic-installation/"><em>Examples</em> page</a>.</p>
<p>There is also a script - <a href="https://github.com/docker-mailserver/docker-mailserver/blob/master/setup.sh"><code>setup.sh</code></a> - supplied with this project. It supports you in configuring and administrating your server. Information on how to get it and how to use it is available <a href="config/setup.sh/">on a dedicated page</a>.</p>
<h3 id="configuration"><a class="toclink" href="#configuration">Configuration</a></h3>
<p>We have a <a href="config/environment/">dedicated configuration page</a>. It contains most of the configuration and explanation you need to setup <em>your</em> mail server properly. Be aware that advanced tasks may still require reading through all parts of this documentation; it may also involve inspecting your running container for debugging purposes. After all, a mail server is a complex arrangement of various programs.</p>
<div class="admonition important">
<p class="admonition-title">Important</p>
<p>If you'd like to change, patch or alter files or behavior of DMS, you can use a script. Just place a script called <code>user-patches.sh</code> in your <code>./docker-data/dms/config/</code> folder volume (which is mounted to <code>/tmp/docker-mailserver/</code> inside the container) and it will be run on container startup. See the <a href="faq/#how-to-adjust-settings-with-the-user-patchessh-script">'Modifications via Script' page</a> for additional documentation and an example.</p>
