Disposable email addressing (DEA) refers to an alternative way of sharing and managing email addressing. DEA sets up a new, unique email address for every contact or entity, making a point-to-point connection between the sender and the recipient. Subsequently, if anyone compromises the address or utilises it in connection email abuse, the address owner can easily cancel (or "dispose" of) it without affecting any of his other contacts. Following the cancellation or replacement of a disposable email address, the (ex-)owner need notify no more than one person/contact of the change. ==Uses== Disposable email addressing sets up a different, unique email address for every sender/recipient combination. It operates most usefully in scenarios where someone may sell or release an email address to spam lists or to other unscrupulous entities. The most common situations of this type involve online registration for sites offering discussion groups, bulletin boards, chat rooms, online shopping, and file hosting services. In a time when email spam has become an everyday nuisance, and when identity theft threatens, DEAs can serve as a convenient tool for protecting Internet users.〔 〕 Disposable email addresses can be cancelled if someone starts to use the address in a manner that was not intended by the creator. Examples are the accidental release of an email to a spam list, or if the address was procured by spammers. Alternatively, the user may simply decide not to receive further correspondence from the sender. Whatever the cause, DEA allows the address owner to take unilateral action by simply cancelling the address in question. Later, the owner can determine whether to update the recipient or not. Disposable email addresses typically forward to one or more real email mailboxes where the owner receives and reads messages. The contact with whom a DEA is shared never learns the real email address of the user. If a database manages the DEA, it can also quickly identify the expected sender of each message by retrieving the associated contact name of each unique DEA. Used properly, DEA can also help identify which recipients handle email addresses in a careless or illegitimate manner. Moreover, it can serve as a good tool for spotting fake messages or phishers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Disposable email address」の詳細全文を読む スポンサード リンク
