DomainKeys Identified Mail (DKIM) is an essential email authentication mechanism that uses public key cryptography to verify that an email message was sent from an authorized domain and hasn't been altered in transit. DKIM authenticates email messages using a private key and a public key that is published in the domain's DNS as a TXT record.
Performing a DKIM record lookup and selector domainkey check is a crucial part of DKIM authentication. These checks ensure that the DKIM record is correctly set up and that email messages are properly authenticated. DKIM record lookup and selector domainkey check can be done using various DKIM verification tools available online.
Another essential part of email authentication is performing an SPF and DKIM check. Sender Policy Framework (SPF) is another email authentication mechanism that checks whether the sending email services are authorized to send emails on behalf of the domain. Receiving servers use SPF and DKIM to verify the authenticity of the email headers and ensure that the email is not fraudulent or a phishing attempt.
DKIM is a crucial part of the DMARC (Domain-based Message Authentication, Reporting, and Conformance) standard. DMARC is a policy that allows domain owners to specify how they would like receiving servers to handle unauthenticated email messages. DKIM is an essential part of the DMARC standard, ensuring that email messages are properly authenticated before being delivered to the recipient.
In conclusion, DKIM is a crucial part of email authentication and a vital part of the DMARC standard. Performing a DKIM record lookup, selector domainkey check, and SPF and DKIM check ensures that email messages are properly authenticated and not fraudulent or a phishing attempt. By using DKIM verification tools, you can easily perform these checks and ensure the security of your email communications.
The selector is a text inserted in the domain, e.g. ‘S=txt,’ to form a unique DNS record for each email sent. The selector allows domains to have multiple keys for signatures created by different date ranges, systems, and external services.
