Hotmail can't verify itself

OK, I know it's like shooting fish in a barrel, but it's time to poke fun at Microsoft once again. The Sender ID framework developed by Microsoft and other industry partners is...

... an e-mail authentication technology protocol that helps address the problem of spoofing and phishing by verifying the domain name from which e-mail is sent. Sender ID validates the origin of e-mail by verifying the IP address of the sender against the purported owner of the sending domain.

In principle, it's a great idea and Microsoft has already started using it with Hotmail which is owned by them. But as my cropped screenshot below shows, they need to work a little bit more on the implementation (click graphic for larger version):


It looks like they forget to register their own servers with Sender ID. Oops.
