In the year after the law was enacted, less than seven per cent of spam complied with the requirements of the legislation, according to MX Logic, an Internet-security firm. Last year, compliance with the law never even reached one per cent. Corporate technology administrators watched, often dumbfounded, as spam volumes jumped noticeably in October, and then again in November. Postini, a prominent Internet-security firm, stopped twenty-two billion messages from reaching the mailboxes of its thirty-six thousand clients in November alone. The company now intercepts twelve spam messages for every e-mail delivered.
