Sender ID is an historic [1] anti-spoofing proposal from the former MARID IETF working group that tried to join Sender Policy Framework (SPF) and Caller ID. Sender ID is defined primarily in Experimental RFC 4406, [2] but there are additional parts in RFC 4405, [3] RFC 4407 [4] and RFC 4408.
Sender Policy Framework (SPF) is an email authentication method that ensures the sending mail server is authorized to originate mail from the email sender's domain. [ 1 ] [ 2 ] This authentication only applies to the email sender listed in the "envelope from" field during the initial SMTP connection.
SPF authenticates the sender IP address. SPF allows the receiver to check that an email claimed to have come from a specific domain comes from an IP address authorized by that domain's administrators. Usually, a domain administrator will authorize the IP addresses used by their own outbound MTAs, including any proxy or smarthost. [7] [8]
The Sender Rewriting Scheme (SRS) is a scheme for bypassing the Sender Policy Framework's (SPF) methods of preventing forged sender addresses. Forging a sender address is also known as email spoofing .
DMARC extends two existing email authentication mechanisms, Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). It allows the administrative owner of a domain to publish a policy in their DNS records to specify how to check the From: field presented to end users and how the receiver should deal with failures, and it provides a ...

DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect forged sender addresses in email (email spoofing), a technique often used in phishing and email spam. DKIM allows the receiver to check that an email that claimed to have come from a specific domain was indeed authorized by the owner of that domain. [1]
