<p>This is a community contributed guide. Please let us know via a Github Issue if you're having any difficulty following the guide so that we can update it.</p>
|
|
<p>This guide is focused on only using <a href="../../../config/security/understanding-the-ports/">SMTP ports (not POP3 and IMAP)</a> with the intent to send received mail to another MTA service such as <em>Gmail</em>. It is not intended to have a MUA client (<em>eg: Thunderbird</em>) to retrieve mail directly from <code>docker-mailserver</code> via POP3/IMAP.</p>
|
|
<p>In this setup <code>docker-mailserver</code> is not intended to receive email externally, so no anti-spam or anti-virus software is needed, making the service lighter to run.</p>
|
|
<div class="admonition warning">

|
<p class="admonition-title">Open Relays</p>
|
|
<p>Adding the docker network's gateway to the list of trusted hosts (<em>eg: using the <code>network</code> or <code>connected-networks</code> option</em>), can create an <a href="https://en.wikipedia.org/wiki/Open_mail_relay"><strong>open relay</strong></a>. For instance <a href="https://github.com/docker-mailserver/docker-mailserver/issues/1405#issuecomment-590106498">if IPv6 is enabled on the host machine, but not in Docker</a>.</p>

<ol>
|
|
<li>
|
|
<p>If you're running a version of <code>docker-mailserver</code> earlier than v10.2, <a href="../../../config/setup.sh/">you'll need to get <code>setup.sh</code></a>. Otherwise you can substitute <code>./setup.sh <command></code> with <code>docker exec mailserver setup <command></code>.</p>
|
|
</li>
|
|
<li>
|
|
<p>Pull the docker image: <code>docker pull docker.io/mailserver/docker-mailserver:latest</code>.</p>
|

</li>

<p>Create the file <code>docker-compose.yml</code> with a content like this:</p>

<p>You may need to open ports <code>25</code>, <code>587</code> and <code>465</code> on the firewall. For example, with the firewall <code>ufw</code>, run:</p>
|

<div class="highlight"><pre><span></span><code>ufw allow <span class="m">25</span>

<p>Configure your DNS service to use an MX record for the <em>hostname</em> (eg: <code>mail</code>) you configured in the previous step and add the <a href="../../../config/best-practices/spf/">SPF</a> TXT record.</p>
|
|
<p>If you manually manage the DNS zone file for the domain, it would look something like this:</p>
|
|
<div class="highlight"><pre><span></span><code>mail IN A 10.11.12.13
|
|
|
|
; mail-server for example.com
|

3600 IN MX 1 mail.example.com.
|
|
|
|
; Add SPF record
|
|
IN TXT "v=spf1 mx ~all"
|
|
</code></pre></div>
|
|
<p>Then don't forget to change the serial number and to restart the service.</p>

<p>Aliases make sure that any email that comes to these accounts is forwarded to your third-party email address (<code>external-account@gmail.com</code>), where they are retrieved (<em>eg: via third-party web or mobile app</em>), instead of connecting directly to <code>docker-mailserer</code> with POP3 / IMAP.</p>

<p>This extra step is required to avoid the <code>553 5.7.1 Sender address rejected: not owned by user</code> error (<em>the accounts used for submitting mail to Gmail are <code>admin.gmail@example.com</code> and <code>info.gmail@example.com</code></em>)</p>
