<h1 id="_1">允许用户无需身份验证发送邮件</h1>
<h2 id="postfix">Postfix</h2>
<p>创建文本文件 <code>/etc/postfix/accepted_unauth_senders</code>,列出无需身份验证就可以
发送邮件的用户邮件地址。下面以用户 <code>user@example.com</code> 为例:</p>
<pre><code>user@example.com OK
</code></pre>
<p>使用 <code>postmap</code> 命令建立哈希数据库文件:</p>
<pre><code># postmap hash:/etc/postfix/accepted_unauth_senders
</code></pre>
<p>修改 Postfix 配置文件 <code>/etc/postfix/main.cf</code> 以使用该文件:</p>
<pre><code>smtpd_sender_restrictions =
check_sender_access hash:/etc/postfix/accepted_unauth_senders,
[...OTHER RESTRICTIONS HERE...]
</code></pre>
<p>重启 postfix 服务以使设置生效:</p>
<pre><code># /etc/init.d/postfix restart
</code></pre>
<h2 id="iredapd">iRedAPD</h2>
<p>iRedAPD 插件 <code>reject_sender_login_mismatch</code> 会检测伪造的发件人地址。如果发件人
的域名在你的服务器托管,并且邮件不是经由 SMTP 验证发送的,就会被认为是伪造的
发件人。这种情况下 iRedAPD 会直接拒收邮件(拒收提示信息为:<code>Policy rejection
not logged in</code>),因此需要在 iRedAPD 里放行将该收件人邮件地址。如果邮件是由
固定的内部网络设备发送(例如,打印机、传真机),可以直接放行 IP 地址。</p>
<ul>
<li>放行发件人邮件地址 <code>user@example.com</code>,请在 <code>/opt/iredapd/settings.py</code>
加以下参数:</li>
</ul>
<pre><code>ALLOWED_FORGED_SENDERS = ['user@example.com']
</code></pre>
<ul>
<li>放行发件人 IP 地址或网段,例如, <code>192.168.0.1</code><code>192.168.1.0/24</code>,请在
<code>/opt/iredapd/settings.py</code> 里加以下参数:</li>
</ul>
<pre><code>MYNETWORKS = ['192.168.0.1', '192.168.1.0/24']
</code></pre>
<p>修改后需要重启 iRedAPD 服务。</p><div class="footer">
