<p>It is <strong>strongly recommended</strong> to <strong>not</strong> use the <code class="docutils literal notranslate"><span class="pre">nameservers</span></code>

<a class="reference external" href="https://1.1.1.1/">Cloudflares public resolvers</a>, which are much faster and more

<p><code class="docutils literal notranslate"><span class="pre">save_aggregate</span></code> and <code class="docutils literal notranslate"><span class="pre">save_forensic</span></code> are separate options
because you may not want to save forensic reports
(also known as failure reports) to your Elasticsearch instance,
particularly if you are in a highly-regulated industry that
handles sensitive data, such as healthcare or finance. If your
legitimate outgoing email fails DMARC, it is possible
that email may appear later in a forensic report.</p>
<p>Forensic reports contain the original headers of an email that
failed a DMARC check, and sometimes may also include the
full message body, depending on the policy of the reporting
organization.</p>
<p>Most reporting organizations do not send forensic reports of any
kind for privacy reasons. While aggregate DMARC reports are sent
at least daily, it is normal to receive very few forensic reports.</p>
<p>An alternative approach is to still collect forensic/failure/ruf
reports in your DMARC inbox, but run <code class="docutils literal notranslate"><span class="pre">parsedmarc</span></code> with
<code class="docutils literal notranslate"><span class="pre">save_forensic</span> <span class="pre">=</span> <span class="pre">True</span></code> manually on a separate IMAP folder (using
the <code class="docutils literal notranslate"><span class="pre">reports_folder</span></code> option), after you have manually moved
known samples you want to save to that folder
(e.g. malicious samples and non-sensitive legitimate samples).</p>

<h2>Multi-tenant support<a class="headerlink" href="#multi-tenant-support" title="Link to this heading"></a></h2>
<p>Starting in <code class="docutils literal notranslate"><span class="pre">8.19.0</span></code>, ParseDMARC provides multi-tenant support by placing data into separate OpenSearch or Elasticsearch index prefixes. To set this up, create a YAML file that is formatted where each key is a tenant name, and the value is a list of domains related to that tenant, not including subdomains, like this:</p>
<div class="highlight-yaml notranslate"><div class="highlight"><pre><span></span><span class="nt">example</span><span class="p">:</span>
<span class="w"> </span><span class="p p-Indicator">-</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">example.com</span>
<span class="w"> </span><span class="p p-Indicator">-</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">example.net</span>
<span class="w"> </span><span class="p p-Indicator">-</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">example.org</span>

<span class="w"> </span><span class="p p-Indicator">-</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">whalensolutions.com</span>
</pre></div>
</div>
<p>Save it to disk where the user running ParseDMARC can read it, then set <code class="docutils literal notranslate"><span class="pre">index_prefix_domain_map</span></code> to that filepath in the <code class="docutils literal notranslate"><span class="pre">[general]</span></code> section of the ParseDMARC configuration file and do not set an <code class="docutils literal notranslate"><span class="pre">index_prefix</span></code> option in the <code class="docutils literal notranslate"><span class="pre">[elasticsearch]</span></code> or <code class="docutils literal notranslate"><span class="pre">[opensearch]</span></code> sections.</p>
<p>When configured correctly, if ParseDMARC finds that a report is related to a domain in the mapping, the report will be saved in an index name that has the tenant name prefixed to it with a trailing underscore. Then, you can use the security features of Opensearch or the ELK stack to only grant users access to the indexes that they need.</p>
