Aserver receives contains DNS TXT records. Each record is linked to a specific domain or range of addressessubdomains belonging to the same network. Here is an example of an SPF DNS TXT record with the authorized domain name vspf includemydomain.com all Today email senders without valid SPF records often go through rigorous authentication checks. And most of them end up in the spam folder. Although SPF authentication can suffice sometimes it doesnt offer full protection from domain spoofing and other malicious email activity. You also need to update the records when you change Internet Service Providers ISPs.

Like SPF DKIM uses DNS TXT records to verify the sender identity. One big difference is that DKIM uses cryptography instead of IP addresses. DKIM relies on two encryption keys one public and one private The private key is accessible only to the domains owner. It creates a digital signature that you attach to your email header. This signature serves to authenticate your outgoing messages. The public key is accessible in the senders DNS server. Recipients use the public key to verify the DKIM signature in the message header.
Diagram of DKIM email authentication process Although DKIM authentication is more secure than SPF they work better together to protect the email sender and receiver. Consider SPF and DKIM the twofactor verification equivalent for email authentication. Related Best Ways to Improve Email Deliverability What is DMARC DMARC Domainbased Message Authentication Reporting Conformance is a validation process that checks both SPF and DKIM records to verify emails. . to have SPF and DKIM protocols in place. If the email passes both checks it gets authenticated. If it doesnt you can set policy parameters to determine how the server should manage the email. You will then receive DMARC reports explaining how the server handled.
