1. A method of automatically resending an electronic message originally sent to a receiving user at a first address that is now invalid to a second address for the receiving user, wherein the second address has been registered with a forwarding address server, the method comprising the steps of:

  • sending an electronic message from a first electronic mail domain to the first address at a second electronic mail domain;

    determining in the second domain that the first address is no longer valid;

    automatically sending a query from the second domain to the forwarding address server to determine a new address associated with the first address, and wherein the forwarding address server stores the first address in association with the second address;

    returning the second address to the second domain; and

    thereafter automatically sending the electronic message to the second address.
