<p>Per default, Dovecot sends a "I'm still here" notification to every client that has an open connection with Dovecot to get mails as quickly as possible without manually polling it (IMAP PUSH). This notification is controlled by the setting <a href="https://wiki.dovecot.org/Timeouts"><code>imap_idle_notify_interval</code></a>, which defaults to 2 minutes. </p>
<p>A short interval results in the client getting a lot of messages for this connection, which is bad for mobile devices, because every time the device receives this message, the mailing app has to wake up. This can result in unnecessary battery drain.</p>
<h2 id="edit-the-value">Edit the value<a class="headerlink" href="#edit-the-value" title="Permanent link">&para;</a></h2>
<h3 id="change-configuration">Change configuration<a class="headerlink" href="#change-configuration" title="Permanent link">&para;</a></h3>
<p>Create a new file <code>data/conf/dovecot/extra.conf</code> (or edit it if it already exists).
Insert the setting followed by the new value. For example, to set the interval to 5 minutes you could type:</p>
<div class="highlight"><pre><span></span><code>imap_idle_notify_interval = 5 mins
</code></pre></div>
<p>29 minutes is the maximum value allowed by the <a href="https://tools.ietf.org/html/rfc2177">corresponding RFC</a>.</p>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>This isn't a default setting in mailcow because we don't know how this setting changes the behavior of other clients. Be careful if you change this and monitor different behavior.</p>
</div>
<h3 id="reload-dovecot">Reload Dovecot<a class="headerlink" href="#reload-dovecot" title="Permanent link">&para;</a></h3>
<p>Now reload Dovecot:
<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow dovecot reload
</code></pre></div></p>
<div class="admonition info">
<p class="admonition-title">Info</p>
<p>You can check the value of this setting with
<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow dovecot -a | grep &quot;imap_idle_notify_interval&quot;
</code></pre></div>
If you didn't change it, it should be at 2m. If you did change it, you should see your new value.</p>
