DomainKeys is an e-mail authentication E-mail authentication is the effort to equip messages of the e-mail transport system with enough verifiable information, so that recipients can recognize the nature of each incoming message automatically. It differs from content filtering system designed to verify the DNS domain A domain name is an identification label that defines a realm of administrative autonomy, authority, or control on the Internet, based on the Domain Name System of an e-mail Electronic mail, commonly called email or e-mail, is a method of exchanging digital messages across the Internet or other computer networks. Email systems are based on a store-and-forward model in which email server computer systems accept, forward, deliver and store messages on behalf of users, who only need to connect to the email infrastructure, sender and the message integrity Data integrity is data that has a complete or whole structure. All characteristics of the data including business rules, rules for how pieces of data relate, dates, definitions and lineage must be correct for data to be complete. The DomainKeys specification has adopted aspects of Identified Internet Mail to create an enhanced protocol The Internet Protocol is a protocol used for communicating data across a packet-switched internetwork using the Internet Protocol Suite, also referred to as TCP/IP called DomainKeys Identified Mail DomainKeys Identified Mail is a method for email authentication that allows an organization to take responsibility for a message in a way that can be validated by a recipient. The organization can be a direct handler of the message, such as the author, the originating sending site or an intermediary along the transit path; or an indirect handler, (DKIM). This merged specification became the basis for an IETF The Internet Engineering Task Force develops and promotes Internet standards, cooperating closely with the W3C and ISO/IEC standards bodies and dealing in particular with standards of the TCP/IP and Internet protocol suite. It is an open standards organization, with no formal membership or membership requirements. All participants and managers are Working Group which guided the specification toward becoming an IETF standard.
Both DomainKeys and DKIM were published in May 2007. DomainKeys was issued as a "historical" protocol and DKIM DomainKeys Identified Mail is a method for email authentication that allows an organization to take responsibility for a message in a way that can be validated by a recipient. The organization can be a direct handler of the message, such as the author, the originating sending site or an intermediary along the transit path; or an indirect handler, was issued as its standards-track replacement.

- Sender ID Sender ID is an anti-spoofing proposal from the former MARID IETF working group that tried to join Sender Policy Framework and Caller ID. Sender ID is defined primarily in Experimental RFC 4406, but additional parts in RFC 4405, RFC 4407 and RFC 4408

- Author Domain Signing Practices In computing Author Domain Signing Practices is an optional extension to the E-mail authentication scheme DKIM, whereby a domain can publish the signing practices it adopts when relaying mail on behalf of associated authors. ADSP was adopted as a standards track RFC 5617 in August 2009
- Sender Policy Framework Sender Policy Framework , as defined in RFC 4408, is an e-mail validation system designed to prevent e-mail spam by addressing a common vulnerability, source address spoofing. SPF allows administrators to specify which hosts are allowed to send e-mail from a given domain by creating a specific DNS SPF record in the public DNS. Mail exchangers then (SPF)
