<p>This tutorial is applicable to iRedMail-1.0 and later releases. If you're
|
|
running an iRedMail-0.9.9 or earlier release, please follow
|
|
<a href="./allow.user.to.send.email.without.authentication.html">this tutorial</a> instead.</p>
|
|
</div>
|
|
<h2 id="postfix">Postfix</h2>
|
|
<p>Open file <code>/etc/postfix/sender_access.pcre</code> (Linux/OpenBSD) or
|
|
<code>/usr/local/etc/postfix/sender_access.pcre</code> (FreeBSD), append the user's email
|
|
address which you're going to allow to send email without smtp
|
|
authentication. We use email address <code>user@example.com</code> for example here.</p>
|
|
<pre><code>/^user@example\.com$/ OK
|
|
</code></pre>
|
|
<p>It's ok to use IP address instead like below if you want to allow all emails
|
|
sent from this IP address:</p>
|
|
<pre><code>/^192\.168\.1\.1$/ OK
|
|
/^192\.168\.2\./ OK
|
|
/^172\.16\./ OK
|
|
</code></pre>
|
|
<div class="admonition attention">
|
|
<p class="admonition-title">Attention</p>
|
|
<ul>
|
|
<li>File <code>sender_access.pcre</code> is in pcre format, check Postfix manual page
|
|
<a href="http://www.postfix.org/pcre_table.5.html">PCRE_TABLE(5)</a> for more details.</li>
|
|
<li>For more allowed sender or IP address/network format, please check
|
|
Postfix manual page: <a href="http://www.postfix.org/access.5.html">access(5)</a>.</li>
|
|
</ul>
|
|
</div>
|
|
<p>Now restart or reload postfix to make it work:</p>
|
|
<pre><code>postfix reload
|
|
</code></pre>
|
|
<h2 id="iredapd">iRedAPD</h2>
|
|
<p>iRedAPD plugin <code>reject_sender_login_mismatch</code> checks forged sender address.
|
|
If sender domain is hosted on your server, but email was sent without smtp
|
|
auth, it's considered as a forged email, and iRedAPD rejects this email
|
|
(with rejection message: <code>SMTP AUTH is required for users under this sender
|
|
domain</code>).</p>
|
|
<ul>
|
|
<li>
|
|
<p>To allow sending email without smtp authentication for user
|
|
<code>user@example.com</code>, please add parameter <code>ALLOWED_FORGED_SENDERS</code> in
|
|
iRedAPD config file <code>/opt/iredapd/settings.py</code> like below. If this parameter
|
|
already exists, please append the user email address in the list.</p>
|
|
<p>You can find default value and detailed comment about this parameter
|
|
in file <code>/opt/iredapd/libs/default_settings.py</code>.</p>
|
|
</li>
|
|
</ul>
|
|
<pre><code>ALLOWED_FORGED_SENDERS = ['user@example.com']
|
|
</code></pre>
|
|
<ul>
|
|
<li>To bypass sender IP address or network, for example, <code>192.168.0.1</code> and
|
|
<code>192.168.1.0/24</code>, please add setting in <code>/opt/iredapd/settings.py</code> like below:</li>
|
|
</ul>
|
|
<pre><code>MYNETWORKS = ['192.168.0.1', '192.168.1.0/24']
|
|
</code></pre>
|
|
<p>Restarting iRedAPD service is required if you updated <code>/opt/iredapd/settings.py</code>.</p><div class="footer">
