From the Spamex FAQ: "Email sent to a Disposable Email Address that has been turned off or deleted is rejected (bounced) with a '550 User Unknown' error. This is the same error that is returned if email is sent to an email address that does not exist. Email rejected because an address is turned off cannotbe retrieved as the service never actually accepted it." How will the e-mail network hold up under anincreasing number of bounce backs as new disposable addresses are created and turned off?
