EmailValidator is a PHP library for verifying email address syntax, format, and DNS records against technical specifications. It functions as a logic-based checker to ensure email addresses follow standard global formatting and communication rules.
The library includes security utilities to identify deceptive characters and spoofing attempts in email addresses. These anti-spoofing tools analyze email strings for Unicode characters that mimic standard Latin letters to prevent fraudulent impersonation.
The project covers domain verification through DNS record checks to confirm a destination server exists and can receive messages. It also provides a composite validation strategy and an interface-based system that allows for the integration of custom validation rules.
