Configure DKIM for Email Authentication
Purpose
DKIM (DomainKeys Identified Mail) helps prevent email spoofing by adding a digital signature to outgoing messages, allowing receiving mail systems to verify that emails genuinely came from your domain and weren't modified in transit.
Implementation
Google Workspace
- Go to Google Admin console.
- Navigate to Apps > Google Workspace > Gmail > Authenticate Email.
- Select your domain and click "Generate new record".
- Copy the DKIM TXT record provided by Google.
- Add this TXT record to your DNS.
- After DNS propagation, return to Admin console and click "Start authentication".
Evidence
- Screenshot of published DKIM DNS record
- Sample email headers showing DKIM pass
