- SPF (Sender Policy Framework):
- SPF enables domain owners to designate authorized mail servers for sending emails on their behalf.
- The SPF record, found in DNS, enumerates the permitted IP addresses for sending emails on the domain’s behalf.
- DKIM (DomainKeys Identified Mail):
- DKIM digitally signs email messages to validate the sender’s authenticity.
- It aids in combating content forgery and bolstering recipient confidence.
- DMARC (Domain-based Message Authentication, Reporting, and Conformance):
- DMARC authenticates emails sent from your email address.
- To achieve DMARC authentication success, emails must pass SPF or DKIM authentication and exhibit domain alignment in the “From:” field.
