<h2>Description<a class="headerlink" href="#description" title="Permalink to this heading"></a></h2>
<p><strong>imtest</strong> is a utility that allows you to authenticate to an IMAP server
and interactively issue commands to it. Once authenticated you may issue
any IMAP command by simply typing it in. It is capable of multiple SASL
authentication mechanisms and handles encryption layers transparently.
This utility is often used for testing the operation of an IMAP server.
Also those developing IMAP clients find it useful.</p>
