This plugin enhances form validation for website administrators by verifying that submitted email addresses contain a legitimate top-level domain (TLD), such as .com or .org. It is designed for developers and site owners who need to improve data quality and reduce spam from incorrectly formatted email submissions.
TLD Validation: Integrates directly with the platform's built-in is_email() function to check the domain suffix against the official IANA root zone database, ensuring only recognized TLDs pass validation.
Simple Activation: Once installed and activated, the validation runs automatically on any form using the standard email validation function, requiring no additional configuration or code changes.
Composer Installation: The plugin is distributed and managed via Composer, making it easy to include and update within modern development workflows that use dependency management.
Reduced Invalid Submissions: By catching typos in domain endings (like .cmo instead of .com) or blocking deliberately fake addresses, it helps maintain cleaner contact lists and user databases.
Dependency Handling: Relies on external libraries for TLD list management and international domain name (IDN) processing, which are automatically handled through its Composer package definition.
