A plugin for Craft CMS that prevents new users from signing up unless their email is from a specific domain.

1. Move emailwhitelist directory to craft/plugins directory
2. Install Email Whitelist under Craft Admin › Settings › Plugins

In the settings page for Email Whitelist, simply add a new row and type the text that any new user's email must have. The plugin will check each item in the list.

There is also a toggle to enable Blacklist Mode, which disallows whatever emails you've put in the list.

Do you also have client-side validation? Great! In a template, you can get the list of allowed emails to throw into a <script> tag:

{% for email in craft.emailWhitelist.getEmails() %}
  {{ email[0] }}
{% endfor %}

On error, the plugin sets a flash message which you can see in a template:

{% if craft.session.hasFlash('emailwhitelist') %}
  <h1>{{ craft.session.getFlash('emailwhitelist') }}</h1>
{% endif %}

That's all there is to it!

• 1.1.0 : Add Blacklist mode, with a toggle on the plugin's Settings page, changed variable names
• 1.0.0 : Initial Version
