December 11, 2006 (Updated) According to a recent Microsoft study, spammers send an average of 3.8 billion messages to Hotmail addresses every day. Thanks to a technology called Sender ID, an average of 20 million of those spam messages are blocked from e-mail inboxes every day.
If you use the following e-mail programs, you're already experiencing increased protection from spam through Sender ID:
• MSN Hotmail
• Windows Live Hotmail
• Microsoft Exchange Server
• Microsoft Office Live Mail
<--- If an e-mail message fails Sender ID, you will see a warning like this one.What is Sender ID?
Sender ID authenticates inbound e-mail to help verify that it is from the person that it says it is from. Messages that have been authenticated by Sender ID are less likely to be spam and messages that fail Sender ID are more likely to be spam. To help distinguish between verifiable and unverifiable senders, Sender ID checks and validates the sender's e-mail address against the sender's Internet Protocol (IP).

Microsoft began implementing Sender ID in MSN Hotmail early in 2005 and has seen positive results. As of April 2007, 8 million domains worldwide have adopted the Sender ID technology.
Momentum for Sender ID adoption is quickly growing. As more Internet and e-mail providers begin to work with this new technology, the ability of Sender ID to intercept spam, phishing attempts, and other online exploits continues to increase.
Also, an increasing number of technology organizations have announced Sender ID support by encouraging industry adoption, publishing their own sender records, or offering specific products and services that support the Sender ID system, from e-mail applications to anti-spam services.
