System and method for secure classification of electronic mail
First Claim
1. A system for generating an extended source address for use with electronic mail (e-mail) between a sender and a recipient, comprising:
- an extension generator module, associated with said sender, that generates a valid extended source address that is based on an identity of said recipient;
an e-mail transmitter, associated with said extension generator module, that transmits said e-mail message containing said valid extended source address to said recipient; and
a message receiver module, associated with said extension generator module, that classifies incoming e-mail messages based on valid extended destination addresses.

Abstract
A system for, and method of, generating an extended source electronic mail (e-mail) address for use between a sender and a recipient and systems and methods for creating e-mail messages having a destination-dependent extended source address structure. In one embodiment, the system includes: (1) an extension generator module, associated with the sender, that generates a valid extended source address that is based on the identity of the recipient, (2) an e-mail transmitter, associated with the extension generator module, that transmits the e-mail message containing the valid extended source address to the recipient and (3) a message receiver module, associated with the extension generator module, that classifies incoming e-mail messages based on valid extended source addresses.

12. A method of generating an extended source address for use with electronic mail (e-mail), comprising:
-
generating, in response to a first e-mail message from said recipient, an valid extended source address that is based on said identity of said recipient;
transmitting a second e-mail message containing said valid extended source address to said recipient for use by said recipient as a destination address in future messages to said sender; and
classifying incoming e-mail messages based on associated valid extended destination addresses. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A mail transfer agent for processing electronic mail (e-mail) between a sender and a recipient, comprising:
-
an extension generator module, associated with said sender, that generates, in response to a first e-mail message from said recipient, an valid extended source address that is based on an identity of said recipient;
a destination lookup module, associated with said extension generator module, that stores said valid extended source address for future use;
a handshake module, associated with said extension generator module, that receives said first e-mail message and manages generation of said valid extended source address; and
a message receiver module, associated with said extension generator module, that classifies incoming e-mail messages based on valid extended source addresses. - View Dependent Claims (24, 25, 26, 27, 28)
