What measures has Congress taken to regulate spam e-mail?

What will be an ideal response?

In 2003, Congress enacted the federal Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN-SPAM Act). The act 1. prohibits spammers from using falsified headers in e-mail messages, including the originating domain name and e-mail address; 2. prohibits deceptive subject lines that mislead a recipient about the contents or subject matter of the message; 3 . requires that recipients of spam be given the opportunity to opt out and not have the spammer send e-mail to the recipient's address; and 4. requires spammers who send sexually oriented e-mail to properly label it as such. The Federal Trade Commission (FTC), a federal administrative agency, is empowered to enforce the CAN-SPAM Act. In effect, the CAN-SPAM Act does not end spam but instead approves businesses to use spam as long as they do not lie.
