À quoi servent SPF, DKIM et DMARC ?
• SPF helps servers verify that messages appearing to come from a particular domain are sent from servers authorized by the domain owner.

• DKIM adds a digital signature to every message. This lets receiving servers verify that messages aren't forged, and weren't changed during transit.
• DMARC enforces SPF and DKIM authentication, and lets admins get reports about message authentication and delivery.
