Email Authentication Explained
SPF (Sender Policy Framework)
SPF specifies which mail servers are authorized to send email for your domain.
DKIM (DomainKeys Identified Mail)
DKIM adds a digital signature to verify emails haven't been modified in transit.

DMARC tells receivers what to do when SPF or DKIM checks fail.
