  • Apparatus and method for electronic mail address portability
    Patent number: 6381634
    Abstract: A method and apparatus for e-mail address portability are provided. A service control point on the Internet comprises an e-mail address database and a transaction processing object. The e-mail address database has at least a well-known-address field for storing a well-known address value and a literal address field for storing a literal address value that corresponds to the well-known-address value. The transaction processing object, when called with an address translation request, accesses the e-mail address database. The address translation request has a well-known address value which is translated to the corresponding literal address value. After the translation, the transaction processing object returns the corresponding literal address value to the calling routine.
