Chapter 2. Neither Confirm nor Deny

The simplest method is to send an email to the address and see whether the message “bounces back.” Many email servers send a message back to the sender if they couldn't deliver the email successfully. You have probably seen this yourself if you mistyped an email address or one of your recipients changed his or her email address.
