DKIM Record Checker
The DKIM record checker from Truelist helps you validate your DKIM (DomainKeys Identified Mail) records for proper email authentication. Enter your domain and selector to analyze your DKIM configuration, public keys, and signature settings instantly.
About DKIM Selectors
DKIM records require a "selector" to identify which key to use. Common selectors include "default", "google", "k1", or "selector1". If you don't know your selector, try the "Scan Common Selectors" button to automatically discover available selectors.
Why use the DKIM record checker?
DKIM records digitally sign your emails to prove authenticity and prevent tampering. Our tool helps you ensure your DKIM records are properly configured and secure.
- verifiedValidate DKIM Keys
- Check if your DKIM public keys are properly formatted and configured according to cryptographic standards.
- keySelector Discovery
- Find DKIM selectors automatically by scanning common selector names used by email service providers.
- errorError Detection
- Identify common DKIM issues like missing keys, invalid algorithms, and configuration problems.
- settingsConfiguration Analysis
- Analyze key types, hash algorithms, service types, and flags to ensure optimal DKIM configuration.
Understanding DKIM Records
DKIM (DomainKeys Identified Mail) is an email authentication method that uses cryptographic signatures to verify email authenticity and prevent tampering.
- descriptionDKIM Record Location
- DKIM records are TXT records published at "selector._domainkey.domain.com" where "selector" is chosen by your email provider.
- keyPublic Key Cryptography
- DKIM uses public-key cryptography with RSA or Ed25519 algorithms to sign email headers and verify authenticity.
- labelSelector Management
- Selectors allow multiple DKIM keys per domain and enable key rotation without changing the main DKIM setup.
- securitySignature Verification
- Email receivers use the DKIM record to verify that email content hasn't been modified during transit.
DKIM Best Practices
Follow these guidelines to implement effective DKIM authentication that improves email deliverability and security.
- check Use Strong Keys
Use RSA keys of at least 2048 bits or Ed25519 keys for strong cryptographic security. Avoid deprecated algorithms.
- check Regular Key Rotation
Rotate DKIM keys periodically for security. Use multiple selectors to enable seamless key rotation without disruption.
- check Test Configuration
Regularly test your DKIM records and verify that email signatures are being generated and validated correctly.
