Critics said the law would lead to more spam messages. US legislation designed to stem the tide of junk e-mails has had little impact on spam, say experts. US e-mail filtering firm Postini said the Can-Spam Act had only made a slight dent in the amount of unwanted mail. It found spam accounted for 79% of all e-mails it processed in January, down from 80% in December 2003. Critics of the US law had predicted it would do little to stop spam and may even encourage some businesses to start sending unsolicited messages.
