How does spoofing occur?
The concept is the user simply changes their outgoing mail to another person’s email address. This results in email(s) being sent that look like they have originated from someone else’s email address. Spoofers can retrieve email addresses by using viruses such as “MyDoom.” The virus essentially grabs email addresses listed on the computer’s email program, or stored in other places on the computer’s hard drive. It then starts using the email addresses it retrieved as outgoing mail addresses to send spam/viruses onto others.
