|

<ul>
|
||
<li>自 iRedMail-<code>0.9.0</code>版起，共享邮箱功能默认开启，用户不需要任何额外的配置。</li>
|
||
<li>
|
||
<p>自 iRedMail-<code>0.7.0</code> 版起，Dovecot 已包含共享邮箱的相关设置，但没有启用。
|
||
只需要按照以下文档中启用 <code>acl</code> 插件的步骤即可启用该功能。</p>
|
||
</li>
|
||
<li>
|
||
<p>请勿混淆<code>共享邮箱</code>和<code>公共邮箱</code>。用户在共享邮箱时必须选择要共享的目录并
|
||
指定共享给谁。</p>
|
||
</li>
|
||
</ul>
|
||
</div>
|
||
<h2 id="_1">共享邮箱</h2>
|
||
<p>要开启邮箱共享功能，请确保 <code>acl</code> 插件已在Dovecot 的配置文件
|
||
<code>/etc/dovecot/dovecot.conf</code> 里启用。以下是配置示例：</p>
|
||
<ul>
|
||
<li>Dovecot-1.2 版：</li>
|
||
</ul>
|
||
<pre><code># Part of file: /etc/dovecot/dovecot.conf
|
||
|
||
protocol lda {
|
||
mail_plugins = ... acl
|
||
}
|
||
|
||
protocol imap {
|
||
mail_plugins = ... acl imap_acl
|
||
}
|
||
</code></pre>
|
||
<ul>
|
||
<li>Dovecot-2.x 版：</li>
|
||
</ul>
|
||
<pre><code># Part of file: /etc/dovecot/dovecot.conf
|
||
|
||
mail_plugins = ... acl
|
||
|
||
protocol imap {
|
||
mail_plugins = ... imap_acl
|
||
}
|
||
</code></pre>
|
||
<p>修改后需重启 Dovecot 服务，以使配置生效。</p>
|
||
<h2 id="_2">测试共享目录</h2>
|
||
<p>示例：将用户 <code>from@domain.ltd</code> 的 <code>Sent</code> 目录共享给用户 <code>testing@domain.ltd</code> 。</p>
|
||
<blockquote>
|
||
<p>注意：不要遗漏 IMAP 命令前面的点 <code>.</code> 号。</p>
|
||
</blockquote>
|
||
<pre><code># telnet localhost 143 # <- 输入此命令
|
||
* OK [...] Dovecot ready.
|
||
|
||
. login from@domain.ltd passwd # <- 输入此命令
|
||
# 使用完整邮件地址和密码登陆
|
||
. OK [... ACL ..] Logged in
|
||
|
||
. SETACL Sent testing@domain.ltd rli # <- 输入此命令
|
||
# 将 Sent 目录共享给 testing@domain.ltd，
|
||
# 具体权限为：读(r, read)，查询(l, lookup)，插入新邮件(i, insert)。
|
||
. OK Setacl complete.
|
||
|
||
^] # <- 按 `Ctrl + ]` 组合键退出 telnet 程序。
|
||
telnet> quit
|
||
</code></pre>
|
||
<p>以用户 <code>testing@domain.ltd</code> 身份登录 Roundcube 或 SOGo webmail，即可看到共享的目录。</p>
|
||
<p>额外信息：</p>
|
||
<ul>
|
||
<li>
|
||
<p>使用 <code>SETACL</code> 命令共享目录后， Dovecot 会在 MySQL 数据库中插入一条记录。</p>
|
||
<ul>
|
||
<li>对于采用 OpenLDAP 后端的用户，此记录保存在 SQL 表 <code>iredadmin.share_folder</code> 中。</li>
|
||
<li>对于采用 MySQL/MariaDB/PostgreSQL 后端的用户，此记录保存在 <code>vmail.share_folder</code> 中。</li>
|
||
</ul>
|
||
</li>
|
||
</ul>
|
||
<pre><code># mysql -uroot -p
|
||
mysql> USE vmail;
|
||
mysql> SELECT * FROM share_folder;
|
||
+-----------------+--------------------+-------+
