DKIM is compatible with existing email infrastructure and works withSPFandDMARCto create multiple layers of security for domains sending emails. Mail servers that don’t support DKIM signatures are still able to receive signed messages without any problems—it’s an optional security protocol, and DK...
DKIM and SPF can be compared to a business license or a doctor's medical degree displayed on the wall of an office — they help demonstrate legitimacy. Meanwhile, DMARC tells mail servers what to do when DKIM or SPF fail, whether that is marking the failing emails as "spam," delivering ...
DKIM, like SPF (Sender Policy Framework), is used to complete DMARC alignment. However, DKIM is superior to the SPF record in the sense that its encryption key won’t break when your email message is forwarded. Regardless, both SPF and DKIM are necessary in order to obtain maximum email ...

Without DKIM, an attacker could hijack messages and send an altered message to the recipient. DKIM works with SPF to ensure the sender is legitimate and the message was not altered during transmission. DKIM and SPF together add security to the email system, a primary communication tool on the...
