Nextfly Domain Restricted Access allows you to restrict post and page access to specific email domains. Users must validate their email address via a unique magic link sent to their inbox.

This plugin is perfect for internal company portals, client-specific pages, or any content that should be accessible only to users with a specific email domain (e.g., @company.com).

Key Features:
* Domain-Based Restriction: Easily whitelist email domains for any post or page.
* Secure Magic Links: Users receive a time-sensitive, one-time-use access link via email.
* No Passwords Required: Simplifies user experience by eliminating the need for passwords.
* Customizable Emails: Configure the email subject and body template.
* Cookie-Based Access: Set how long access remains valid (default: 7 days).
* Developer Friendly: Includes hooks for extending functionality.
