\part{Cyrus IMAP Specific IMP Config}
There are a couple of gotchas to watch out for when configuring Horde IMP to work with Cyrus IMAP.

\section{Virtual Hosts}
When using Cyrus configured for virtual hosts, and the standard IMP config, folder handling appears to be broken.

To make virtual hosts work with Cyrus you had to put \texttt{unixhierarchysep: yes} in your imapd.conf - you already knew that part, right? ;) -> this is not correct, Cyrus works at my server with multiple virtual hosts without reconfiguring the unixhierarchysep.

Given this, a change is required in the \texttt{imp/config/servers.php} file: edit that file and make sure you use a slash (/) after the 'INBOX' in namespace instead of the usual dot (.):

<pre><code>
    ...
    'namespace' => 'INBOX/',
    ...
</code></pre>
This is no longer required with IMP 4.1 or later, because namespaces are detected automatically in newer versions.
