Everlytic DMARC, DKIM and SPF Configuration - Domain Authentication

SPF (Sender Policy Framework) helps prevent email spoofing by allowing domain owners to specify which mail servers are authorized to send email on behalf of their domain. DKIM (DomainKeys Identified Mail) adds a digital signature to your email headers, enabling the recipient's server to verify that the email has not been altered during transit and that it indeed comes from your domain. DMARC (Domain-based Message Authentication, Reporting, and Conformance) builds on SPF and DKIM. It allows domain owners to specify how receiving mail servers should deal with emails that fail SPF or DKIM checks.
