EEmailSmtpValidator validates that the attribute value is a valid e-mail address, using SMTP.

It is heavily based on SMTP_validateEmail and uses Net/DNS on plattforms without getmxrr.

This validator should be considered as an improvement of EEmailValidator.

Citing the author of the SMTP email validation class: "this class is meant to be a secondary validation of an email address after the email syntax is validated. It can also provide intermediate email validation before sending a confirmation email to the email address, which does not provide user feedback if the email is invalid - and thus loss of users."
