Microsoft Submits Email Caller ID to the IETF

NetWizard writes "Following on the heels of Yahoo submitting DomainKeys, Microsoft decided to submit their "Caller ID" anti-spam proposal as a draft to the IETF. This proposal tries to tie in IP addresses to the domain of the sender just like SPF does. To make things even more interesting, looks like SPF and MSFT's Caller-ID proposals are merging. On a related note, Yahoo submitted an IPR disclosure for DomainKeys to the IETF."
