WAHOO!!! FINALLY!  Our ISPs are going to help release us from at least a little spam and heck up their stocks value at the same time ;-)  Now we just need to figure out how to get China and South Korea to pay for e-mail comming out of their country...  Geesh Out GDP would shoot through the roof!  Just from spam payments :-P

Five of the largest ISPs in the US are to start charging businesses for guaranteed delivery of their emails, in a bid to combat spam.

Goodmail Systems, which provides a service called CertifiedEmail, has signed up Comcast, Cox Communications, Time Warner Cable's Road Runner and Verizon as customers. Emails certified using the system are marked with a blue ribbon to show they come from a trusted source, thus bypassing spam filters - a privilege that will cost the sender a quarter of a US cent per email.

The voluntary scheme is aimed at large corporations and financial institutions whose mass mailings are most likely to be spoofed and caught in spam filters. Not-for-profit groups will be able to use the service for roughly a tenth of the commercial rate.

Goodmail's chief executive, Richard Gingras, said: "With spam and phishing hitting historic highs even in the last six months, we have seen the limits of technologies which attempt to filter out the bad email. Consumers want their email system to let them know which email is real and safe to open and act on."

Peter Castleton, director of Verizon's consumer broadband services, said phishing and fraud are eroding trust in email as a medium. "A certification service, such as CertifiedEmail, enables us to help restore that trust and makes it easier for consumers to identify legitimate email messages," he said.

According to Goodmail, seven US ISPs are now using CertifedEmail, accounting for 60 per cent of the US population. Goodmail - which takes up to 50 per cent of the revenue generated by the scheme - will for now only approve mail sent by companies and organisations that have been operational for a year or more. Ordinary users can still apply to be whitelisted by individual ISPs, which effectively provides the same trusted status.
