Syntax and format checking ensures that the email meets certain basic criteria such as whether it contains the ‘@’ symbol within the email address.


Domain checking ensures that the email address contains a valid internet domain name, and validates if the featured domain is configured to accept mail.


This function checks that the address segment before the ‘@’ sign is a valid mailbox. This is the clever part, and what sets our service apart from many others.
