Submission + - Are e-mail failure notices legally required? 5
An anonymous reader writes: One of our vendors claims not to have received a series of e-mails, because the address to which the messages were sent was deactivated months ago. We received no failure notice for any message; in fact, even today when choosing any random string of letters for the username, no e-mail sent to the vendor's domain produces a failure notice in response. Is the vendor legally obligated to provide notice of failure to deliver e-mail messages sent to its domain? If no such notice is provided, can we support an argument that our messages have indeed been "received" by the vendor?
