<h1>Email Gathering with Fetchmail</h1>
<p>To enable the <a href="https://www.fetchmail.info">fetchmail</a> service to retrieve e-mails set the environment variable <code>ENABLE_FETCHMAIL</code> to <code>1</code>. Your <code>docker-compose.yml</code> file should look like following snippet:</p>
<div class="highlight"><pre><span></span><code><span class="nt">environment</span><span class="p">:</span>
<span class="p p-Indicator">-</span> <span class="l l-Scalar l-Scalar-Plain">ENABLE_FETCHMAIL=1</span>
<span class="p p-Indicator">-</span> <span class="l l-Scalar l-Scalar-Plain">FETCHMAIL_POLL=300</span>
</code></pre></div>
<p>Generate a file called <code>fetchmail.cf</code> and place it in the <code>docker-data/dms/config/</code> folder. Your <code>docker-mailserver</code> folder should look like this example:</p>
<div class="highlight"><pre><span></span><code>├── docker-data/dms/config
│   ├── dovecot.cf
│   ├── fetchmail.cf
│   ├── postfix-accounts.cf
│   └── postfix-virtual.cf
├── docker-compose.yml
└── README.md
</code></pre></div>
<h2 id="configuration"><a class="toclink" href="#configuration">Configuration</a></h2>
<p>A detailed description of the configuration options can be found in the <a href="https://www.fetchmail.info/fetchmail-man.html">online version of the manual page</a>.</p>
<h3 id="imap-configuration"><a class="toclink" href="#imap-configuration">IMAP Configuration</a></h3>
<div class="admonition example">
<p class="admonition-title">Example</p>
<div class="highlight"><pre><span></span><code>poll &#39;imap.gmail.com&#39; proto imap
user &#39;username&#39;
pass &#39;secret&#39;
is &#39;user1@example.com&#39;

</code></pre></div>
</div>
<h3 id="pop3-configuration"><a class="toclink" href="#pop3-configuration">POP3 Configuration</a></h3>
<div class="admonition example">

is &#39;user2@example.com&#39;

</code></pre></div>
</div>
<div class="admonition caution">
<p class="admonition-title">Caution</p>
<p>Dont forget the last line! (<em>eg: <code>is 'user1@example.com'</code></em>). After <code>is</code>, you have to specify an email address from the configuration file: <code>docker-data/dms/config/postfix-accounts.cf</code>.</p>
</div>
<p>More details how to configure fetchmail can be found in the <a href="https://www.fetchmail.info/fetchmail-man.html#31">fetchmail man page in the chapter “The run control file”</a>.</p>
<h3 id="polling-interval"><a class="toclink" href="#polling-interval">Polling Interval</a></h3>
<p>By default the fetchmail service searches every 5 minutes for new mails on your external mail accounts. You can override this default value by changing the ENV variable <code>FETCHMAIL_POLL</code>:</p>
<div class="highlight"><pre><span></span><code><span class="nt">environment</span><span class="p">:</span>
<span class="p p-Indicator">-</span> <span class="l l-Scalar l-Scalar-Plain">FETCHMAIL_POLL=60</span>
</code></pre></div>
<p>You must specify a numeric argument which is a polling interval in seconds. The example above polls every minute for new mails.</p>
<h2 id="debugging"><a class="toclink" href="#debugging">Debugging</a></h2>
<p>To debug your <code>fetchmail.cf</code> configuration run this command:</p>
<div class="highlight"><pre><span></span><code>./setup.sh debug fetchmail
</code></pre></div>
<p>For more informations about the configuration script <code>setup.sh</code> <a href="../../setup.sh/">read the corresponding docs</a>.</p>
<p>Here a sample output of <code>./setup.sh debug fetchmail</code>:</p>
