The Controlling the Assault of Non-Solicited Pornography and Marketing Act --
CAN-SPAM for short -- require that senders of unsolicited e-mail include return
e-mail addresses where recipients can write to opt out of further mailings.
If the spammer continues to send unsolicited e-mail to that person's address,
he or she will be fined $10 per e-mail, up to $500,000. Courts finding spammers
who "willingly and knowingly" violated the law could impose fines of
up to $1.5 million.
The law also imposes a criminal penalty of up to one year in jail for spammers
who include misleading header information in unsolicited commercial e-mails.
