Understanding DKIM

DKIM (DomainKeys Identified Mail) is an email authentication method designed to detect forged sender addresses in emails. It allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain. This is done by affixing a digital signature linked to a domain name to each outgoing email.

Why is DKIM Important?

  • Email Security: DKIM helps protect your domain from email spoofing, which can be used for phishing attacks and other fraudulent activities.
  • Improved Deliverability: Emails signed with DKIM are less likely to be marked as spam, improving the chances that your messages reach the intended recipients.
  • Brand Integrity: By ensuring that your emails are authenticated, you help maintain the trust and integrity of your brand.

Frequently Asked Questions

DKIM (DomainKeys Identified Mail) is an email authentication method that allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain. It uses a digital signature linked to a domain name.

DKIM helps protect your domain from email spoofing, which is used in phishing attacks and other fraudulent activities. By verifying that emails are sent from authorized servers, DKIM improves email security and deliverability.

DKIM works by adding a digital signature to the header of an email. This signature is created using a private key. The recipient’s mail server retrieves the corresponding public key from the sender’s DNS records to verify the signature.

A DKIM selector is a string used to specify the public key to be used for a specific email. It allows domain owners to rotate keys by publishing multiple public keys in their DNS records.

You can generate a DKIM key pair using tools like OpenSSL or various online DKIM key generators. The key pair consists of a private key, which is kept secure on your mail server, and a public key, which is published in your DNS records.

The DKIM validation process checks the DKIM record for correct formatting, verifies the digital signature using the public key, and ensures the key size and other parameters meet security standards.

A DKIM public key record is a DNS TXT record that contains the public key used to verify the DKIM signature of an email. It is associated with a specific selector and domain.

To add a DKIM record to your DNS, create a new TXT record with the name format [selector]._domainkey.[your-domain] and paste the public key value into the record. Save the record to publish it.

Common DKIM configuration errors include missing DKIM records, incorrect formatting of the public key, weak key sizes, and mismatched selectors.

It is recommended to rotate your DKIM keys periodically, such as every 6-12 months, to maintain security. This involves generating new key pairs and updating the DNS records accordingly.
