Joe JobA form of e-mail spoofing where someone uses your e-mail server to send mass quantities of e-mails. Usually owners and administrators of the e-mail server will become aware of the spoofing when they receive more than the usual quantities of failed delivery notices.
The phrase Joe Job was coined by an attack at Joes.com in January of 1997. A spammer using the free services of Joes.com had been barred from use and sought revenge against those responsible. The spammer's revenge was felt across the Web via a flood of spoofed e-mails sent out in the name of Joes.com in attempt to enrage recipients into taking action against the company's Web site, which, indeed they did.
