A firm called Yahoo! has released a new standard which it says if it is adopted by anyone else could make it harder for spammers who now will not be able to hide behind legitimate locking email. Dubbed DomainKeys, the technology embeds outgoing messages with an encrypted digital signature matched to a signature on the server. ISPs could use the signatures on incoming messages and block those that do not match up. Email users would not see the system because it would only be used by e-mail providers. According to a Yahoo webpage (www.antispam.yahoo.com/domainkeys) ISPs would have the power to block fraudulent "phishing" attacks, in which scam artists attempt to collect credit card numbers and other information by posing as legitimate outfits.
