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 (38)

16. The remailer as recited in claim 15 wherein said alias source address generator employs a real source address of said e-mail message and said destination address to generate said alias source address.
17. The remailer as recited in claim 16 wherein said alias source address generator compresses said real source address to generate said alias source address.
