An E-mail verification class written by PHP

This class can be used to check whether emails are effectively using the SMTP protocol.

It can be connected to the SMTP server defined in the MX record verified by the domain name of the address.

And simulate the delivery of the message to see if it is accepted as valid at the given recipient address.
