It works but you have to choose the reply and not reply all to send the e-mail only to the user submited email.
You just have to take this out of the webriti-smtp-mail.php file.
// Set Reply To Field
$phpmailer->AddReplyTo(webriti_smtp_mail_from_email(), webriti_smtp_mail_from_name());
Now it will only send the message email.
