Spoofing in IT (Information Technology)

                  The term spoofing is also sometimes used to refer to header forgery, the insertion of false or misleading information in e-mail or netnews headers. Falsified headers are used to mislead the recipient, or network applications, as to the origin of a message. This is a common technique of spammers and sporgers, who wish to conceal the origin of their messages to avoid being tracked down.

Making an e-mail message appear to have come from one place to when really it comes from another is called spoofing. It is generally used by spammers, who do not want their real address to appear on the e-mails they send. Since the messages they send out have web links in them, they do not care if people click ‘reply’ and send an e-mails to the wrong place. It also makes it a lot harder for ISP to track them down and close their accounts.
