Sender ID is Not an Anti-Spam Solution

"Microsoft recently announced it will more heavily utilize its Sender ID technology when filtering email sent to its Hotmail service. Anti-spam expert and http://www.spambutcher.com founder, Rich Olson is skeptical how much this will do to combat spam. "The biggest misunderstanding about Sender ID is that it's a general anti-spam solution,” Olson said. “It's not, and Microsoft doesn't claim that it is. Its main purpose is to certify that an email message actually came from the claimed sender."" Source: eMediaWire.com
