A 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. [Source: SitePoint]
