Dave Smith

This class can validate email address and compute quality score.

It can send a HTTP request to the mailboxlayer API Web server to validate a given email address.

The mailboxlayer API can check the email domain MX records to connect to the domain SMTP server and depending on the response returns a quality score for the validity of the email address.
