GoDMARC free DKIM technology protects message legitimacy by configuring the email server with a special DKIM digital signature for the emails you send. The emails are verified in transit by the recipient servers through DKIM keypair, alternatively known as private and public keys, placed on the sender and receiver’s DNS, respectively.
The signature acts like a watermark that helps the recipient servers recognize that a message actually came from your domain and has not been tampered with on the way.
DKIM record makes your brand messages legitimate and streamlines spoofed emails identification. DKIM mechanism works in real-time. Additionally, your recipient server can still validate user emails even without incorporating DMARC or DKIM solutions.
DKIM system not only validates domain identity but also allows users to take additional measures, like reject, deliver, or quarantine the arriving mail.
Domain Key Identified Mail Record Look Up verifies the DKIM selector, stated in your signature header, which shows you the location of the Public Key of the DKIM Keypair in the DNS. The tool performs a test on the domain name and selector to validate published DKIM Keypair.
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.
