Email Caller ID

The majority of email spam and a good percentage of email-borne viruses and other malware spoof the source address. That means that the address it appears to originate from is not its true source. Some may seem as if they come from a friend, coworker or someone else you know. According to an article on TechWeb, Microsoft is gaining some industry support for their Sender ID authentication scheme. With the Sender ID framework email could be blocked or filtered if the "caller ID" of the email does not match up with the source it claims to be from.
