The federal government's two-year-old antispam law is helping to cut back on unsolicited bulk e-mail, but more must be done to fight the problem. Those are the conclusions of a Federal Trade Commission report, released today, on how well the law is working.

The 116-page report , titled "Effectiveness and Enforcement of the CAN-SPAM Act," is the FTC's first assessment of federal antispam efforts since the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003 (CAN-SPAM) took effect. It touts the FTC's accomplishments, outlines new challenges, and advocates passage of an additional law that would give the FTC broader authority to go after international spammers.
