Self Destructing Email

First there was invisible ink, a boon for anyone in the espionage trade who wanted to keep their words a secret. Then in the 1960s Mission Impossible introduced television viewers to messages on cassette tapes that would self-destruct five seconds after being listened to. Now an American company has invented technology to produce the 21st century equivalent, vanishing emails. New York firm VaporStream guarantees messages will disappear in a puff of virtual smoke after being read once. The company's bosses believe the service will be popular with high-profile businesses which are trying to safe guard corporate secrets. But they admit it could help those involved in shady dealings as well, who might have other reasons for not wanting a permanent record of their dealings. Both sender and receiver must be subscribes to use the technology. They use their usual email addresses, but when routed through the self - destruct portal, the names of sender and receiver vanish and so does the message after being read once. The message cannot be copied, forwarded, or edited, and there is no record of it anywhere on any computer. It is much like a telephone call, in the sense that it doesn't leave a record, but it has the convenience of email.
