Microsoft had it's own invention called "Caller ID for Email" that was later merged into "Sender ID" which is a (IMO) defective bastardization of SPF and Caller ID for Email. DKIM emerged from Yahoo!'s DomainKeys specification and addresses the problem from a completely different viewpoint; instead of specifying machines allowed to relay for a domain, DKIM provides cryptographically-secure evidence that a message passed through a "responsible" relay. Unlike SPF, DKIM can validate the From: header field. DMARC adds feedback to DKIM/SPF so that domain owners can see if their domain is being abused (for example, in phishing attacks.) Every single one of these protocols has defects that make them completely useless for combatting spam and mostly useless for combatting phishing. Welcome to Internet email.
