There are a number of different email authentication protocols available, each with its own strengths and weaknesses. Some of the most popular protocols include: DomainKeys Identified Mail (DKIM): DKIM is an email authentication protocol that allows the sender to sign their emails with a digital signature. This signature can be verified by the recipient's email server, which helps to ensure that the email is actually from the sender who claims to have sent it. Sender Policy Framework (SPF): SPF is an email authentication protocol that allows a domain owner to specify which servers are authorized to send email on behalf of their domain.
This helps to prevent email spoofing, as mail servers can check the SPF record for a domain to see if the sender's server is authorized to send email from that domain. Domain-based Message Authentication, Reporting and Conformance (DMARC): DMARC is an email authentication protocol that builds on DKIM and SPF. DMARC allows domain owners to specify how they want email that fails DKIM or SPF authentication to be handled. This
