Electronic mail has become an extremely importantand popular means of communication.

　　The convenience and efficiency of electronicmail are threatened by the extremely rapid growthin the volume of unsolicited commercial electronicmail. Unsolicited commercial electronic mail iscurrently estimated to account for over half of allelectronic mall traffic, up from an estimated 7 percent in 2001, and the volume continues torise. Most of these messages are fraudulent or deceptive in one or more respects.

　　The receipt of unsolicited commercial electronic mail may result in costs to recipients whocannot refuse to accept such mail and who incur costs for the storage of such mail, or for thetime spent accessing, reviewing, and discarding such mail, or for both. The receipt of a largenumber of unwanted messages also decreases the convenience of electronic mall and createsa risk that wanted electronic mail messages, both commercial and noncommercial, will be lost,overlooked, or discarded amidst the larger volume of unwanted messages, thus reducing thereliability and usefulness of electronic mail to the recipient. Some commercial electronic mailcontains material that many recipients may consider vulgar or pornographic in nature.

　　The growth in unsolicited commercial electronic mail imposes significant monetary costson providers of Internet access services, businesses, and educational and nonprofit institutionsthat carry and receive such mail, as there is a finite volume of mail that such providers,businesses, and institutions can handle without further investment in infrastructure. Manysenders of unsolicited commercial electronic mail purposefully disguise the source of suchmall.

　　Many senders of unsolicited commercial electronic mall purposefully include misleadinginformation in the messages' subject lines in order to induce the recipients to view themessages. While some senders of commercial electronic mail messages provide simple andreliable ways for recipients to reject (or 'opt-out' of) receipt of commercial electronic mallfrom such senders in the future, other senders provide no such 'opt-out' mechanism, orrefuse to honor the requests of recipients not to receive electronic mail from such senders inthe future, or both.

　　Many senders of bulk unsolicited commercial electronic mail use computer programs togather large numbers of electronic mail addresses on an automated basis from Internetwebsites or online services where users must post their addresses in order to make full use ofthe website or service.

　　The problems associated with the rapid growth and abuse of unsolicited commercialelectronic mall cannot be solved by the government alone. The development and adoption oftechno-logical approaches and the pursuit of cooperative efforts with other countries will benecessary as well.
