Definitions

  • the present invention relates to a system and method for forwarding electronic messages, and more particularly, relates to forwarding e-mail messages intended to be initially delivered to an obsolete or disfavored address to a chosen forwarding address associated with the obsolete e-mail address.
  • ISP Internet Service Provider
  • AOL America Online
  • Netcom Netcom
  • Redconnect an internet based e-mail service
  • juno rocketmail
  • yahoo internet based e-mail service
  • the e-mail address is unique to the e-mail service provider.
  • the uniqueness of an address to a selected provider is often apparent on the face of the address, e.g., DQuine@aol.com, Quine@juno.com or DouglasQuine@yahoo.com.
  • a user or subscriber to a particular e-mail service may from time to time desire or need to change service providers (e.g., from DQuine@aol.com to QuineDo@pb.com).
  • Exemplary motivation for these changes may derive from the fact that an alternative service provider charges lower rates, or the existing provider's inability to upgrade its service.
  • a user who desires to change from one e-mail service provider to another suddenly faces the reality of being bound to the old service provider because the user's address is unique to that one provider.
  • a sudden and complete changeover is in many circumstances impossible because the community of people who wish to send electronic messages to the user are only aware that the old address exists.
  • an e-mail address may be published in an industry directory that is only published once every year or two years.
  • the e-mail address may be printed on a business card which cannot be retracted and corrected.
  • the user incurs a potentially significant loss of prospective business by abandoning the old address.
  • Some service providers offer their user-subscribers the option of a message forwarding sen/ice. These forwarding services operate by receiving the incoming message, retrieving the portion of the incoming message that identifies a selected user who subscribes to the forwarding service, associating the selected user with a forwarding address through the use of a lookup table, and transmitting the message to the forwarding address.
  • the forwarding services differ from the normal message delivery service that the central service provider offers because a portion of the forwarding address belongs to another central service provider.
  • the forwarded message is actually delivered to its intended recipient by the other or second service provider, i.e., the forwarded message passes through two central service providers, as opposed to just one provider.
  • the intended message recipient is free to change the second provider with regularity provided that the recipient always informs the forwarding service of each change in the second provider.
  • this message forwarding system only works with viable e-mail address, that is, the e-mail address associated with the first service provider must still be active and not obsolete.
  • few e-mail services offer forwarding services and few, if any, offer to forward e- mail after the account is closed. Otherwise, the first service provider is only enabled to send the later mentioned MAIL DAEMON message back to the original sender of the e-mail message.
  • the present invention relates to a method and system for forwarding an e-mail message intended to be delivered to a first e-mail address to a second e-mail address in the event the first e-mail address is disfavored.
  • An e-mail forwarding computer is located at a third e-mail address that is programmable to associate disfavored e-mail addresses with forwarding e-mail addresses.
  • a user at a first computer sends an e-mail message to a first e-mail address at a second remote computer.
  • this e-mail message is returned to the user at the first computer, the user resends the e-mail that was originally addressed to a first e-mail address to a second e-mail forwarding computer that is capable of forwarding the e-mail message to a second e-mail address.
  • the second computer receives the e-mail message and parses the first e-mail address from the e-mail message to determine if there is a second e-mail address associated with the first e- mail address. If there is a second e-mail address associated with the first e-mail address, the second computer sends the e-mail message to a third computer associated with the second e-mail address.
  • an advantage of the present invention is that there is no cooperation needed by the e-mail server associated with the disfavored e-mail address. That is, if an e-mail address becomes disfavored (it is no longer an active e-mail address) either because the associated e-mail server ceases to exist, or the e-mail account has been left abandoned for a host of reasons, the present invention e-mail forwarding system nevertheless operates because no cooperation is needed from the later e-mail server.
  • An additional benefit is that when an e-mail message is forwarded by the present invention, the privacy of the recipient is protected because the sender of the e-mail message is preferably not notified of the recipient's forwarding address.

  • Messaging forwarding system 44 preferably includes a PC 46 connected to an internet service provider 48, which PC 46 is provided with a unique e-mail address (corrections@emailangel.com) and software programmed to perform the below described steps necessary to operate the present invention e-mail forwarding system 44.
  • Internet service provider 48 is preferably connected to INTERNET 22 via router 50.
  • system 44 includes a software program that includes a look-up table 50, which is programmable by users to provide an e-mail forwarding address 52 associated with pre-programmed defunct (undeliverable) e-mail address[es] 54.

  • a “subscriber” of system 44 refers to anyone who subscribes to the e-mail forwarding service of system 44 in which the subscriber registers both a defunct e- mail address 54 and at least one e-mail forwarding address 52 with system 44.

  • a subscriber of system 44 closes an e-mail account (e.g., user@oldaccount.com) for what ever reason, the subscriber may however still desire to continue to receive messages sent to that address (e.g., user@oldaccount.com), but now wants to receive those messages at a different account (e.g., subscriber@newaccount.com).

  • the subscriber now merely accesses the subscriber's designated account in system 44, via any known means such as the internet, registers the defunct e-mail address (e.g., user@oldaccount.com) and associates it with a desired forwarding e-mail address (e.g., subscriber@newaccount.com).

If the account is not a valid account (e.g., quine@luv-npi.com) then the identified e-mail server 26 (e.g., Iuv-npi.com) rejects the request (step 108) and sends a MAIL-DAEMON message 510 (Fig. 5b) to the sender's 14 e-mail server 18 indicating that the message is not deliverable (step 110).

If yes, forwarding system 44, sends the e-mail message 510 addressed to the recipients defunct address 54 (e.g., quine@luv-npi.com) to the recipient subscriber's new e-mail address 52 (e.g., quine@docsense.com) as prescribed in the look-up table 50 of the forwarding system 44. Preferably, forwarding system 44 then sends an e-mail to the sender 14 indicating that the message original addressed to a defunct e-mail address has now been properly forwarded.

Abstract

L'invention concerne un système et un procédé permettant d'acheminer, vers une seconde adresse électronique, un message électronique destiné à une première adresse électronique, dans le cas où cette dernière est une adresse électronique défavorisée (54). Un message électronique, initialement adressé à une première adresse électronique, est envoyé d'un premier ordinateur vers un deuxième ordinateur (200) capable de réexpédier ledit message électronique vers une seconde adresse électronique. Le deuxième ordinateur reçoit le message électronique (202) et analyse la première adresse électronique du message électronique (204) pour établir s'il y a une association entre une seconde adresse électronique et la première adresse électronique (206). Dans l'affirmative, le deuxième ordinateur envoie un message électronique à un troisième ordinateur associé à la seconde adresse électronique (210).
