Registration vs Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

Registration Email Blocker is a WordPress plugin that restricts which email domains can be used for user registration on your website. The plugin was developed to help Russian website owners partially comply with Federal Law No. 406-FZ regarding user authorization requirements. How this plugin helps with compliance: Federal Law 406-FZ requires Russian websites to use specific authorization methods (phone numbers, ESIA, or Russian-controlled systems). While the law does not directly address email-based registration, using foreign email services (gmail.com, yahoo.com, etc.) during registration may contradict the spirit of the law. This plugin helps in the following ways: * Prevents registration with foreign email domains (blacklist mode) * Allows registration only with approved domains (whitelist mode) * Identifies existing users with non-compliant email addresses * Sends notifications to users requesting email change * Provides audit logs of all registration attempts Important Legal Notice: This plugin is a technical tool and does not guarantee full compliance with Federal Law 406-FZ. The plugin addresses only the email domain aspect of user registration. Website owners remain responsible for ensuring full legal compliance. We recommend consulting with a lawyer regarding applicable legislation. The plugin helps eliminate one potential compliance issue but does not replace proper legal authorization systems required by law. Key Features Two Operation Modes: Blacklist (block specific domains) or Whitelist (allow only specific domains) Flexible Enforcement: Hard blocking or warning mode Existing User Management: Automatically identifies users with non-compliant email addresses Bulk Email Notifications: Send email change requests to affected users Detailed Logging: Complete history of registration attempts with IP addresses and timestamps WooCommerce Integration: Controls email domains during registration and checkout Domain Statistics: Analyzes email domains used across all site users CSV Export: Export list of users with non-compliant emails Pre-configured Domain Lists: Ready-to-use lists of popular foreign and Russian email services Administrator Exclusion: Option to exempt administrators from domain checks Who Needs This Plugin Russian website owners required to comply with Federal Law 406-FZ Administrators who need to control user registration WooCommerce stores operating in Russia with customer email requirements Technical Details Works with standard WordPress registration Full WooCommerce compatibility Multisite compatible Translation ready GDPR considerations included Legal Compliance Notice Federal Law 406-FZ Compliance: Federal Law No. 406-FZ (adopted July 26, 2023) establishes requirements for user authorization on Russian websites. The law requires authorization through: 1. Mobile phone numbers 2. ESIA (Unified Identification and Authentication System) 3. Biometric identification system 4. Russian-controlled information systems This plugin addresses the email domain aspect of user registration by preventing the use of foreign email services and encouraging the use of Russian email providers. However, email-based registration is not explicitly addressed in the law. What This Plugin Does: * Prevents registration with foreign email domains (gmail.com, yahoo.com, etc.) * Allows only approved Russian email domains (mail.ru, yandex.ru, etc.) * Identifies and notifies existing users with non-compliant emails * Provides audit logs for compliance verification What This Plugin Does NOT Do: * Does not implement phone number authorization * Does not integrate with ESIA * Does not provide biometric identification * Does not guarantee full legal compliance with Federal Law 406-FZ Responsibility: Website owners are solely responsible for ensuring full compliance with Federal Law 406-FZ and all applicable legislation. This plugin is a technical tool that may assist with partial compliance but should not be considered a complete legal solution. We strongly recommend consulting with a lawyer regarding your specific compliance requirements. Support Development This plugin is completely free and will always remain free.
