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 ]
In the early 1980s, when Simple Mail Transfer Protocol (SMTP) was designed, it provided for no real verification of sending user or system. This was not a problem while email systems were run by trusted corporations and universities, but since the commercialization of the Internet in the early 1990s, spam, phishing, and other crimes have been found to increasingly involve email.
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.

DMARC operates by checking that the domain in the message's From: field (also called "RFC5322.From" [2]) is "aligned" with other authenticated domain names.If either SPF (specified using the aspf field) or DKIM (specified using the adkim field) alignment checks pass, then the DMARC alignment test passes.

Domainkeys, DKIM's predecessor, had an Outbound Signing policy consisting of a single character, "-" if a domain signs all email, and "~" otherwise. [10] DKIM intentionally avoided signers' policies considerations, so that DKIM does not validate a message's "From" field directly , but is a policy-neutral authentication protocol.
