This plugin provides precise control over who can create an account on your site by restricting registration based on email address. It is designed for site administrators running private communities, corporate networks, educational platforms, or any site requiring a verified user base.

• Broad Platform Support: Works with standard user registration, Multisite networks, BuddyPress, BuddyBoss, WooCommerce, and major membership plugins like Paid Memberships Pro and Ultimate Member.
• Flexible Matching Rules: Allow users by full domain names (example.com), domain extensions (.edu), or specific email addresses, with one entry per line in the settings.
• Administrative Control: Configure rules from a central settings panel and customize the error message shown to users attempting to register with a disallowed email.
• Spam Reduction: By limiting registrations to known domains, it helps prevent automated spam account creation.
• Developer Hooks: Includes action and filter hooks, such as one that fires when validation fails, allowing for custom notifications or extended functionality.
