Abstract
Abstract A system for, and method of, generating an alias source address for an electronic mail ("e-mail") message having a real source address and a destination address and a computer network, such as the Internet, including the system or the method. In one embodiment, the system includes an alias source address generator that employs the destination address to generate the alias source address. The system further includes an alias source address substitutor that substitutes the alias source address for the real source address. This removes the real source address from the e-mail message and thereby renders the sender, located at the real source address, anonymous. Further-described are systems and methods for forwarding reply e-mail and filtering reply e-mail based on alias source address.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
58 words
A system for generating an alias source address for an electronic mail
message having a real source address and a destination address, comprising: an alias source address generator arranged to employ said destination
address to generate said alias source address; and an alias source address inserter arranged to place said alias source
address in said electronic mail message.
Claim 2
Dependent Claim
33 words
The system as recited in Claim 1 wherein said alias source address
generator employs a real source address of said electronic mail message and said
destination address to generate said alias source address.
Claim 3
Dependent Claim
24 words
The system as recited in Claim 2 wherein said alias source address
generator compresses said real source address to generate said alias source address.
Claim 4
Independent Claim
26 words
The system as recited in any of the preceding claims wherein said
alias source address generator employs a secret key to generate said alias source
address.
Claim 5
Independent Claim
54 words
The system as recited in any of the preceding claims further
comprising: a real source address generator arranged to generate a real source address
from said alias source address; and a real source address inserter, coupled to said real source address
generator, arranged to place said real source address in said electronic mail message.
Claim 6
Dependent Claim
62 words
The system as recited in Claim 6 wherein said real source address
inserter is arranged to substitute said real source address for said alias source address,
said real source address generator and inserter capable of cooperating to allow
electronic mail directed to said alias source address to be routed to said real source
address, said system functioning as an electronic mail forwarder.
Claim 7

alias source address inserter is arranged to substitute said alias source address for said
real source address, said real source address being removed from said message.
Claim 10
Dependent Claim
53 words
A remailer for coupling to at least one of a plurality of computer
systems of a computer network, for generating an alias source address for, and
remailing, an electronic mail message, comprising: a system as recited in Claim 9 and data transmission circuitry that remails said electronic mail message to
said destination address.
Claim 11
Independent Claim
58 words
A method of generating an alias source address for an electronic mail
message having a real source address and a destination address, comprising the steps of: generating said alias source address based on said destination address;
and substituting said alias source address for said real source address,
wherein said real source address is removed from said e-mail message.
Claim 12
Dependent Claim
35 words
The method as recited in Claim 11 wherein said step of employing
comprises the step of employing a real source address of said e-mail message and said
