Editing SPF, DKIM, and DMARC Authentication (section)

== Introduction ==
Email authentication is the process of verifying that the emails sent from your domain are legitimate and not from unauthorized users or spammers. Implementing '''SPF''' (Sender Policy Framework), '''DKIM''' (DomainKeys Identified Mail), and '''DMARC''' (Domain-based Message Authentication, Reporting & Conformance) is crucial, especially as email providers enhance their security measures against phishing and spoofing. Without proper authentication, your emails may end up in spam folders or fail to be delivered altogether.

These protocols work together:
- '''SPF''' specifies which servers can send emails on behalf of your domain.
- '''DKIM''' adds a cryptographic signature to your emails, verifying legitimate senders.
- '''DMARC''' establishes a policy for handling emails that fail SPF or DKIM checks.

By setting up these authentication methods, you improve your email deliverability, enhance security, and bolster your brand's reputation.
