Atlanta-based EarthLink Inc., the country's third-largest provider of for-pay e-mail accounts, will roll out test versions of the system for its 5 million subscribers this month. Known as "challenge-response" technology, the system thwarts the ability of spammers to reach their intended audience with millions of automatically generated e-mails. When someone sends an e-mail to a challenge-response user, he or she gets an e-mail back asking to verify that the sender is a live person. <snip> -- ((Udhay Shankar N)) ((udhay @ pobox.com)) ((www.digeratus.com)) ------ End of Forwarded Message And LOS ALTOS, Calif.--(BUSINESS WIRE)--May 7, 2003--Mailblocks today announced that it has filed suit against EarthLink Inc. for patent infringement of its Challenge/Response technology, which eliminates email spam from users' inboxes. According to Mailblocks, EarthLink initiated discussions with Mailblocks in connection with its soon-to-be-launched service a short while ago. Based on information presently available, Mailblocks says it appears that the EarthLink service, as advertised, will infringe patent rights held by Mailblocks. The suit was filed today in the United States District Court for the Central District of California. "Mailblocks developed and owns the patents for Challenge/Response, and we intend to vigorously enforce our rights to the fullest extent permitted by law," said Phil Goldman, Mailblocks' CEO. Mailblocks' patented Challenge/Reponses technology eliminates spam generated by computers by assuring that only email sent by humans is placed in a user's email inbox. Email sent from new people who are not in the user's electronic email address book are placed in a Pending folder and automatically sent a request to authenticate (called a Challenge). Machine-generated email cannot reply to the Challenge email, so that message is not sent to the user's inbox. New users need to respond only once to a Challenge in order to be recognized in the future. When users wish to receive email that will be computer-generated, such as confirmations of email purchases or newsletter subscriptions, they can use a special email address to automatically allow those emails to be sent directly to their inbox. ------------------------------------- You are subscribed as interesting-people () lists elistx com To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/
