<h1>Virtual Domains<a class="headerlink" href="#virtual-domains" title="Permalink to this headline">¶</a></h1>
<div class="section" id="what-are-virtual-domains">
<h2>What are virtual domains?<a class="headerlink" href="#what-are-virtual-domains" title="Permalink to this headline">¶</a></h2>
<p>Virtual domains means hosting a service for more than one
domain on a single server. Cyrus IMAP has the ability to host IMAP/POP
mailboxes for multiple domains (for example: <code class="docutils literal notranslate"><span class="pre">test@cyrusisgreat.org</span></code> and
<code class="docutils literal notranslate"><span class="pre">test@ilovecyrus.com</span></code>) on a single server or Murder.</p>
<p>Cyrus needs to know which domain to use when a mailbox is accessed.
There are two ways in which Cyrus can determine the domain:</p>
<dl class="simple">
<dt>Fully qualified userid</dt><dd><p>The client logs in with a userid
containing the domain in which the user belongs (for example:
<code class="docutils literal notranslate"><span class="pre">test@cyrusisgreat.org</span></code> or <code class="docutils literal notranslate"><span class="pre">test@ilovecyrus.com</span></code>)</p>
</dd>
<dt>IP address</dt><dd><p>The server looks up the domain based on the IP
address of the receiving interface (useful for servers with multiple
NICs or those using IP aliasing)</p>
</dd>
</dl>
<p>If the <code class="docutils literal notranslate"><span class="pre">virtdomains</span></code> option is set to <code class="docutils literal notranslate"><span class="pre">off</span></code> (or <code class="docutils literal notranslate"><span class="pre">no</span></code>, <code class="docutils literal notranslate"><span class="pre">0</span></code>, <code class="docutils literal notranslate"><span class="pre">false</span></code>),
Cyrus does not know or care about domains, and only ever considers the local
part of email addresses. This configuration is never recommended, but is
currently the default.</p>
<p>If the <code class="docutils literal notranslate"><span class="pre">virtdomains</span></code> option is set to <code class="docutils literal notranslate"><span class="pre">userid</span></code>, then only the
fully qualified userid is used. This is the only recommended configuration
for new deployments, and in the future may become the default or only option.
Existing deployments should strongly consider migrating towards this
configuration.</p>
<p>If the <code class="docutils literal notranslate"><span class="pre">virtdomains</span></code> option is set to <code class="docutils literal notranslate"><span class="pre">on</span></code> (or <code class="docutils literal notranslate"><span class="pre">yes</span></code>, <code class="docutils literal notranslate"><span class="pre">1</span></code>, <code class="docutils literal notranslate"><span class="pre">true</span></code>),
Cyrus uses both mechanisms to work out the domain (with the fully qualified
userid taking precedence). This configuration is not recommended.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>If you are providing calendaring services, you MUST use the
<code class="docutils literal notranslate"><span class="pre">virtdomains:</span> <span class="pre">userid</span></code> configuration. Calendaring services require
a consistent single authoritative fully-qualified email address for
each user in order to function, and this is the only configuration
that provides it.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">virtdomains:</span> <span class="pre">off</span></code> and <code class="docutils literal notranslate"><span class="pre">virtdomains:</span> <span class="pre">on</span></code> configurations both
allow users’ domains to be changed from outside of Cyrus without Cyrus
knowing about it, which fundamentally breaks calendaring. These
configurations are only suitable for IMAP-only deployments.</p>

<h2>Concepts<a class="headerlink" href="#concepts" title="Permalink to this headline">¶</a></h2>
<dl>
<dt>Everyone is in a domain</dt><dd><p>It’s best to think of every user as existing inside a domain. Unqualified users are technically inside the <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code>.</p>
</dd>
<dt>Names can be qualified</dt><dd><p>Global admins can reference mailboxes and IDs by qualified names. That is, for any given mailbox command, you can add <code class="docutils literal notranslate"><span class="pre">@domain</span></code> to the end of the mailbox name.</p>
<p>Here are some examples:</p>
<blockquote>
<div><ul class="simple">

<dt>Domains are mutually exclusive</dt><dd><p>Users only have access to mailboxes within their own domain (intra-domain). The following

</ul>
</div>
<div class="section" id="configuration">
<h2>Configuration<a class="headerlink" href="#configuration" title="Permalink to this headline">¶</a></h2>
<p>Support for virtual domains is enabled by turning on the <code class="docutils literal notranslate"><span class="pre">virtdomains</span></code> option in <a class="reference internal" href="../../reference/manpages/configs/imapd.conf.html#std-cyrusman-imapd.conf-5">imapd.conf(5)</a>.</p>
<p>When upgrading from a single domain installation to a virtual
domain installation, the name of the existing domain (domain of the
server hostname) should be specified using the <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code>
option in <a class="reference internal" href="../../reference/manpages/configs/imapd.conf.html#std-cyrusman-imapd.conf-5">imapd.conf(5)</a>. This allows users to continue to
access their mailboxes using unqualified userids. For example, if the
primary IP address on your server resolves to ‘www.xxx.yyy.zzz’,
then set <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code> to ‘xxx.yyy.zzz’.</p>
<p>Even for new installations, set the <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code> to the “real”
domain of the server (domain of its primary hostname).
See <a class="reference internal" href="#administrators">Administrators</a> for further discussion.</p>
<p>Here is a sample <code class="docutils literal notranslate"><span class="pre">imapd.conf</span></code> with a minimal set of configuration
options:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">configdirectory</span><span class="p">:</span> <span class="o">/</span><span class="n">var</span><span class="o">/</span><span class="n">imap</span>
<span class="n">partition</span><span class="o">-</span><span class="n">default</span><span class="p">:</span> <span class="o">/</span><span class="n">var</span><span class="o">/</span><span class="n">spool</span><span class="o">/</span><span class="n">cyrus</span>
<span class="n">admins</span><span class="p">:</span> <span class="n">admin</span> <span class="n">lukecage</span><span class="o">.</span><span class="n">admin</span><span class="nd">@hisdomain</span><span class="o">.</span><span class="n">com</span> <span class="n">mercedesknight</span><span class="o">.</span><span class="n">admin</span><span class="nd">@herdomain</span><span class="o">.</span><span class="n">net</span>
<span class="n">virtdomains</span><span class="p">:</span> <span class="n">yes</span>
<span class="n">defaultdomain</span><span class="p">:</span> <span class="n">exampleisp</span><span class="o">.</span><span class="n">net</span>
</pre></div>
</div>
<p>This example has three domains: exampleisp.net, hisdomain.com, and
herdomain.net. <code class="docutils literal notranslate"><span class="pre">admin</span></code> can administer all three domains, while
<code class="docutils literal notranslate"><span class="pre">lukecage.admin@hisdomain.com</span></code> and
<code class="docutils literal notranslate"><span class="pre">mercedesknight.admin@herdomain.net</span></code> can only administer their respective
domains.</p>
<p>Everyday users should not be administrators. In the
above example, Mercedes Knight and Luke Cage have separate administrative accounts for
their domains.</p>
<div class="section" id="multiple-ip-addresses">
<h3>Multiple IP Addresses<a class="headerlink" href="#multiple-ip-addresses" title="Permalink to this headline">¶</a></h3>
<p>In order to use a multiple IP address configuration, the server must
be able to do a reverse lookup on the IP address to determine the
hostname of the receiving interface. For example:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="mf">192.168</span><span class="o">.</span><span class="mf">0.1</span> <span class="o">-></span> <span class="n">mail</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">com</span>
<span class="mf">192.168</span><span class="o">.</span><span class="mf">0.2</span> <span class="o">-></span> <span class="n">mail</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">net</span>
<span class="mf">192.168</span><span class="o">.</span><span class="mf">0.3</span> <span class="o">-></span> <span class="n">mail</span><span class="o">.</span><span class="n">foo</span><span class="o">.</span><span class="n">bar</span>
</pre></div>
</div>
<p>Once the server obtains the fully qualified hostname of the
interface, it removes the localpart (i.e., ‘mail’) and uses the
remainder as the domain for any user that logs in.</p>
<p>This address to hostname mapping would usually be done via DNS,
<code class="docutils literal notranslate"><span class="pre">/etc/hosts</span></code>, NIS, etc. Configuration of the various naming
services is beyond the scope of this document.</p>

<div class="section" id="delivering-mail">
<h3>Delivering mail<a class="headerlink" href="#delivering-mail" title="Permalink to this headline">¶</a></h3>
<p>To deliver mail to your virtual domains, configure your MTA so that

<p>Some items to be aware of:</p>
<ul>
<li><p>It is easiest to use the mailertable to route mail to Cyrus,
rather than adding the domain to the local-host-names file ($w).
This prevents Sendmail from changing the domain name to the local host name.</p>

</li>
<li><p>You’ll have to use the Cyrus mailer in LMTP mode, and you’ll have
to change the mailer flags so that it provides the full domain while
communicating via LMTP. Specifically these changes:</p>

<h3>Mail Clients<a class="headerlink" href="#mail-clients" title="Permalink to this headline">¶</a></h3>
<p>The only changes you’ll need to make to mail clients is to change

The <code class="docutils literal notranslate"><span class="pre">user%example.com</span></code> form of userid is also supported.</p>

fully qualified userid in the <code class="docutils literal notranslate"><span class="pre">admins</span></code> option
(e.g., <code class="docutils literal notranslate"><span class="pre">admin@example.net</span></code>) and only have access to mailboxes in
the associated domain. Mailbox names should be specified in the same
fashion as on a single domain configuration.</p>
<p>Global administrators are specified with an unqualified userid in the
<code class="docutils literal notranslate"><span class="pre">admins</span></code> option and have access to <em>any</em> mailbox on the
server. Because global admins use unqualified userids, they belong
to the <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code>. As a result, you CANNOT have a global
admin without specifying a <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code>. Note that when
trying to login as a global admin to a multi-homed server from a remote
machine, it might be necessary to fully qualify the userid with the
<code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code>.</p>
<p>Global admins must use <code class="docutils literal notranslate"><span class="pre">mailbox@domain</span></code> syntax when
specifying mailboxes outside of the <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code>. Examples
(using <code class="docutils literal notranslate"><span class="pre">cyradm</span></code>):</p>
<p>To create a new INBOX for user ‘test’ in <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code>:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">cm</span> <span class="n">user</span><span class="o">.</span><span class="n">test</span>
</pre></div>
</div>
<p>To create a new INBOX for user ‘test’ in domain ‘example.com’:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">cm</span> <span class="n">user</span><span class="o">.</span><span class="n">test</span><span class="nd">@example</span><span class="o">.</span><span class="n">com</span>
</pre></div>
</div>
<p>To list all mailboxes in domain ‘example.com’:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">lm</span> <span class="o">*</span><span class="nd">@example</span><span class="o">.</span><span class="n">com</span>
