<p>要修改邮件附件大小，需要修改三个地方。</p>
<h2 id="postfix">修改 postfix 中邮件大小的设置</h2>
<p>Postfix 是一个邮件传送代理（MTA），因此，要修改配置以使它能传送大附件的邮件。</p>
<p>假设要修改附件大小为 100MB，需对 <code>message_size_limit</code> 做如下修改：</p>
<pre><code># postconf -e message_size_limit='104857600'
</code></pre>
<p>之后重启 Postfix 服务，使上述修改生效:</p>
<pre><code># /etc/init.d/postfix restart
</code></pre>
<p><strong>注意</strong>:</p>
<ul>
<li><code>104857600</code> 是由 100 (MB) x 1024 (KB) x 1024 (Bit) 计算得到的结果。</li>
<li>邮件在发送前会被客户端（Outlook，Thunderbird等）重新编码，导致邮件大小会超过
100MB，所以建议将上述设置中的邮件大小改为 110MB 或 120MB 即可。</li>
</ul>
<p>这样你就可以通过客户端正常发送邮件了。</p>
<h2 id="roundcube">修改 Roundcube 网页邮箱的附件上传大小</h2>
<p>如果使用 Roundcube 网页邮箱，需要额外更改两个地方：</p>
<h3 id="php">修改 PHP 设置允许上传大附件</h3>
<p>修改 PHP 配置文件 <code>/etc/php.ini</code> 中的 <code>memory_limit</code>， <code>upload_max_filesize</code> 和 <code>post_max_size</code> 三个参数：</p>
<ul>
<li>在 RHEL/CentOS 系统上: 配置文件路径是 <code>/etc/php.ini</code></li>
<li>在 Debian/Ubuntu 系统上，配置文件路径是 <code>/etc/php5/apache2/php.ini</code></li>
<li>在 FreeBSD 系统上，配置文件路径是 <code>/usr/local/etc/php.ini</code> （Apache），或者是 <code>/etc/php5/fpm/php.ini</code> （Nginx）。</li>
<li>在 OpenBSD 系统上，配置文件路径是 <code>/etc/php-5.4.ini</code>。如果你运行的 PHP 版本号为 5.4 ，路径将会不一样。</li>
</ul>
<pre><code>memory_limit = 200M;
upload_max_filesize = 100M;
post_max_size = 100M;
</code></pre>
<h3 id="roundcube_1">修改 Roundcube 网页邮箱设置以允许上传大附件</h3>
<p>修改 roundcube 目录下的 <code>.htaccess</code> 文件:</p>
<ul>
<li>在 RHEL/CentOS 系统上，此文件路径为 <code>/var/www/roundcubemail/.htaccess</code></li>
<li>在 Debian/Ubuntu 系统上，此文件路径为 <code>/usr/share/apache2/roundcubemail/.htaccess</code> 或者
<code>/opt/www/roundcubemail/.htaccess</code>.</li>
<li>在 FreeBSD 系统上，此文件路径为 <code>/usr/local/www/roundcubemail/.htaccess</code></li>
<li>在 OpenBSD 系统上，此文件路径为 <code>/var/www/roundcubemail/.htaccess</code></li>
</ul>
<p>注意:某些 Linux/BSD 发行版本可能没有 <code>.htaccess</code> 文件，此时你可以忽略此步骤。</p>
<pre><code>php_value memory_limit 200M
php_value upload_max_filesize 100M
php_value post_max_size 100M
</code></pre>
<p>重启 Apache 或 php-fpm 服务以使上述修改生效。</p>
<h2 id="nginx">修改 Nginx 上传文件大小</h2>
<p>在配置文件 <code>/etc/nginx/nginx.conf</code> 中找到参数 <code>client_max_body_size</code> ，按需要修改大小：</p>
<p>```
