System and method for preserving delivery status notification when moving from a native network to a foreign network
First Claim
1. A method for transferring and preserving delivery status notification information that is sent from a first network into a second network comprising the steps of:
- receiving an e-nail message from said first network having associated therewith delivery status notification information that identifies a return notification that should be returned to the sender upon occurrence of at least one specific event relating to the status of delivery of the message;
mapping the received delivery status notification information into the closest delivery status notification option supported by said second network and storing said mapped delivery status notification information in order to permit said second network to generate the return notification should said at least one specific event take place within said second network; and
preserving the original delivery status notification information received from the first network by encoding it at the second network and by associating the encoded deliver status notification information in a fashion that will permit the encoded delivery status notification information to be transparently transferred along with the associated message without causing the second network to act on the encoded delivery status notification information.

Abstract
This invention is directed to systems and methods for preserving delivery status notification information as a message transits from one type of network to another type of network. For incoming messages, the present invention takes a two-pronged approach whereby the delivery status notification information accompanying the incoming message is 1) mapped to the closest available options supported by the network and 2) preserved so that the original information may be fully recovered without loss at a later time. When messages are delivered within the network, the mapped delivery status notification information will generate the closest delivery status notifications supported by the network. For outgoing messages, the preserved delivery status notification information is extracted and used to set delivery status notification options. If the message is being transferred to the same type of network that originated the message, using the preserved delivery status notification information results in the original options being fully restored without loss of any kind. If the message is being sent to a different network than that generated the message, using the original delivery status notification information will result in the closest available options being selected. This two-pronged approach taken by the present invention minimizes the mapping losses under all circumstances.

2. A computer-readable medium having computer-executable instructions encoded thereon for implementing a method for transferring and preserving delivery status notification information that is sent from a first network into a second network and wherein the method is comprised of the steps of:
-
receiving an e-mail message from said first network having associated therewith delivery status notification information that identifies a return notification that should be returned to the sender upon occurrence of at least one specific event relating to the status of delivery of the message; mapping the received delivery status notification information into the closest delivery status notification optional supported by said second network and storing said mapped delivery status notification information in order to permit said second network to generate the return notification should said at least one specific event take place within said second network; and preserving the original delivery status notification information received from the first network by encoding it at the second network and by associating the encoded delivery status notification information in a fashion that will permit the encoded delivery status notification information to be transparently transferred along with the associated message without causing the second network to act on the encoded delivery status notification information.

7. A method as defined in claims wherein if said message is transferred out of said second network then performing at least the step of retrieving said stored delivery status notification information and placing said retrieved delivery status notification information with said message so that said delivery status notification accompanies said message out of second network.

8. A method for transferring and preserving delivery status notification information that is sent from a first network into a second network comprising the steps of;
-
receiving an e-mail message from said first network having associated therewith delivery status notification information that identifies a return notification that should be returned to the sender upon occurrence of at least one specific event relating to the status of delivery of the message; mapping the received delivery status notification information into the closest delivery status notification option supported by said second network and storing said mapped delivery status notification information in order to permit said second network to generate the return notification should said at least one specific event take place within said second network; and saving the original delivery status notification information received from the first network so that the original delivery status notification information can be recovered and returned to the same state as it was when received from said first network. - View Dependent Claims (10, 11, 12, 13)
