MX Validation: Checks for valid Mail Exchange (MX) records to confirm the email domain is configured to receive messages, ensuring it exists and is active.
MX Blacklist Validation: Identifies domains listed on known blacklists for spam or malicious activity, helping you avoid unreliable or harmful email destinations.
