<p class="p">You can configure your Zendesk Support instance to be open, closed, or restricted (see <a class="xref" href="https://support.zendesk.com/hc/en-us/articles/4408887573274" target="_blank">Understanding options for end-user access and sign-in</a>). This article describes how to set up a <em class="ph i">restricted</em> Zendesk Support
instance, so you can control end-user access through approved email domains. </p>
<p class="p">This means that your Help Center is visible to all users, but only users with email addresses
in domains that you approve can register and submit support requests. Any unapproved user’s
support request will be either be completely rejected or sent to the Suspended Tickets
queue.</p>
