DKIM Lookup

A sophisticated email authentication technique called DKIM (DomainKeys Identified Mail) aids in thwarting phishing attempts, email spoofing, and unwanted email changes. In order for the recipient's mail server to confirm the sender's legitimacy and guarantee that the email content is not changed during transmission, it adds a distinct cryptographic signature to outgoing emails. The sending mail server uses a private key to create a DKIM signature, which is then embedded in the email's header. To verify the signature, the recipient's server next obtains the matching public key from the sender's domain's DNS records. The email is seen as authentic and is less likely to be flagged as spam if the verification process is successful.Email deliverability, domain reputation, and email security are all improved by implementing DKIM. To weed out malicious emails, a number of email providers, such as Microsoft, Yahoo, and Gmail, check DKIM signatures. DKIM offers a strong protection against email fraud when used in conjunction with SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting, and Conformance). To confirm your domain's DKIM data and guarantee correct email authentication, use our DKIM lookup tool. Keep your domain safe and your email correspondence using DKIM trustworthy!

Frequently Asked Questions

Find answers to the most commonly asked questions below.

What is DKIM?

DKIM (DomainKeys Identified Mail) is an email authentication method that helps verify that an email was sent from an authorized server and has not been modified in transit. It uses cryptographic signatures to ensure email integrity and prevent spoofing.

How does DKIM work?

DKIM works by signing outgoing emails with a private key. The recipient’s mail server then retrieves the public key from the sender’s DNS records to validate the email’s authenticity. If the signature matches, the email is considered genuine.

Why is DKIM important?

DKIM (DomainKeys Identified Mail) is important because it helps prevent email spoofing and ensures the integrity of emails sent from your domain. It works by adding a cryptographic signature to outgoing emails, allowing the recipient's mail server to verify that the email was genuinely sent from your domain and hasn’t been altered in transit. This improves email deliverability, enhances security, and helps protect against phishing attacks.

How can I check if my DKIM is working?

You can use a DKIM lookup tool to check if your DKIM record is correctly set up. Simply enter your domain name, and the tool will verify the DKIM signature and key.

What is the difference between DKIM, SPF, and DMARC?

  • SPF (Sender Policy Framework): Defines which mail servers are allowed to send emails on behalf of a domain.
  • DKIM (DomainKeys Identified Mail): Uses cryptographic signatures to verify email integrity..
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance): Enforces SPF and DKIM policies and provides reporting on email authentication failures.

How do I set up DKIM for my domain?

  • Generate a DKIM key pair (private and public keys).
  • Add the DKIM public key as a TXT record in your domain’s DNS settings.
  • Enable DKIM signing on your mail server.
  • Test and verify DKIM using a DKIM lookup tool.

What happens if DKIM fails?

If DKIM verification fails, the recipient’s mail server may treat the email as suspicious, increasing the chances of it being marked as spam or rejected.

Do all email providers support DKIM?

Most major email providers, including Gmail, Yahoo, Outlook, and Microsoft Exchange, support DKIM for email authentication.
