DomainKeys Identified Mail (DKIM) is a method for email senders to digitally sign email messages in a way that can be verified by email receivers. This allows receivers to verify that the message truly came from the sender, and has not been tampered with. DKIM is intended to address some of the flaws in the existing email system, such as spoofing, phishing, and message tampering.
For your domains, Salsa Labs does support and advise DKIM authentication. For details on how to activate the protocol, contact their support team directly.
Skysnag helps busy engineers enforce DMARC, responds to any misconfigurations for SPF or DKIM which increases email deliverability, and eliminates email spoofing and identity impersonation.
