Joe-job
Spam sent with spoofed headers to harm the victim's reputation
A 'Joe-job' is when a spam campaign is rigged with forged 'from' and 'reply-to' headers, to imply that the spam emails originated from the victim company or individual, thus tarnishing their reputation.
Joe-job mails may carry obvious scams, such as 419 scams or phishing attempts, but often carry simple spamvertising for something inappropriate - for example an anti-spam firm. Just such an attack took place in 2007, when spammers carried out a large-scale joe-job attack on anti-spam organisation Spamhaus, sending out millions of mails pretending to promote their services.
