What is DKIM (DomainKeys Identified Mail)?
Email authentication method that uses digital signatures to prevent email spoofing and ensure sender authenticity. Technical standard used by email providers. Essential for email deliverability. Implemented by IT teams to improve email security and reduce spam.
DKIM authentication adds digital signatures to emails to verify sender identity and prevent spoofing. It's crucial for email deliverability and security, working alongside SPF and DMARC protocols to protect against email fraud and maintain sender reputation.
Implement DKIM by generating public/private key pairs, adding DNS records, and configuring email servers. Work with IT teams to properly set up DKIM signatures and verify implementation through testing tools.
Common DKIM issues include key rotation challenges, configuration errors, and alignment failures. Regular monitoring, proper key management, and understanding authentication reports help maintain effective DKIM implementation.
