CAN-SPAM has not stemmed the tide of spam that devours inboxes. The CAN-SPAM act, which defines spam as bulk mail, does not use the word spam in its textual body, and the industry defines spam in an entirely other way. CAN- SPAM does not count the number of messages, but instead will call 1 or a million messages spam if its requirements are not met. Therefore, IT managers will have to remain in close communication with business marketing and advertising departments to ensure that all e-mail complies with CAN-SPAM. Commtouch Software and Finjan Software have not perceived much advantage from the enactment of CAN-SPAM, with Commtouch reporting that its detection centers had no substantial change in the number of spam attacks through January 8, 2004, while Finjan did have lower numbers, which are attributed to a temporary regrouping. Postini also reports that spam is not decreasing. 'eWeek' Labs puts considerable importance on reinforcement of e-mail guidelines by IT. CAN-SPAM requires an opt- out method. However, 'eWeek' Labs is convinced that unscrupulous spammers will work harder to confirm valid e-mail addresses. Therefore, IT managers should maintain the master opt-out list to avoid situations where commercial e-mail is sent to an opt-out address. Companies also have to ensure the correctness of header, subject line, and return e-mail addresses, get opt-out addresses off the list within 10 business days, conspicuously identify ad or solicitation e-mail as such, and include the postal address of the sender in commercial e-mail.
