Unsolicited advertising by electronic means (commercial e-mail)

Requires senders of unsolicited advertising e-mail to provide a toll-free number or return e-mail address for opting out, to honor opt-outs, and to begin the subject line with "ADV:" ("ADV: ADLT" for adult material). It also bans distributing software built to falsify e-mail routing information. The statute says it becomes inoperative when federal law regulates unsolicited commercial e-mail, which raises a real question about its current force after CAN-SPAM (2003).
