Proposed authentication standard that is a merged proposal between the authors of SPF and Microsoft's Caller ID.
An authentication scheme, similar to SPF, sponsored by Microsoft. See "SPF."
Sender ID is an authentication protocol used to verify that the originating IP address is authorized to send email for the domain name declared in the visible "From" or "Sender" lines of the email message. Sender ID is used to prevent spoofing and to identify messages with visible domain names that have been forged.
The informal name for a new anti-spam program combining two existing protocols: Sender Policy Framework and CallerID. SenderID authenticates email senders and blocks email forgeries and faked addresses.
The Sender ID Framework is an email authentication technology protocol that helps address the problems of spoofing and phishing by verifying the domain name from which email is sent. Sender ID validates the origin of email by verifying the IP address of the sender against the purported owner of the sending domain.
Sender ID is an anti-spam proposal from the former MARID IETF working group that joined Sender Policy Framework (SPF) and Caller ID. It was accepted as an Experimental RFC by the Internet Engineering Task Force, as is, on December 8th, 2005 based on wide industry support and adoption.
