The Sender ID Framework, as Microsoft calls it, comprises three separate specifications: Sender Policy Framework (SPF), Caller ID for e-mail, and Submitter Optimization. Briefly, here's how it works: The Domain Name System (DNS) maintains SPF records for domains. When an e-mail message is received by the inbound mail server, the server looks up the sending domain's published DNS record and determines whether the sending server's IP address matches the one on record. If the record matches, the e-mail is authenticated and delivered to the recipient; otherwise, the message is either discarded or returned to the sender as bounce e-mail.
