Some senders would be charged under new plan by Yahoo, AOL

"AOL and Yahoo said the program, which is being offered through a company called Goodmail Systems, will target banks, online retailers and other groups that send large amounts of e-mail. In exchange for a payment and a pledge to contact only people who have agreed to receive their messages, the companies would be ensured their e-mails aren't diverted to spam folders or have images or Web addresses filtered out."
