DKIM (DomainKeys Identified Mail)

DKIM (DomainKeys Identified Mail) is an email authentication method that allows the sender to attach a digital signature to each email, helping to verify the sender’s domain and ensure that the email has not been altered.

The DKIM signature is added to the email header and can be verified by the recipient’s mail server. This helps prevent email spoofing and phishing by confirming that the email is genuinely from the claimed sender and has not been tampered with during transit. Implementing DKIM enhances email deliverability and protects against fraud.
