What is DKIM and full form of DKIM?
DKIM (DomainKeys Identified Mail) is an Email Validation System used for authenticating the message sender while providing a layer of security and authenticity. DKIM is used to verify whether a message sent is actually from the sender it claims to be from.
DKIM ensures that the content of the message has not been changed in transit. This helps in preventing different types of email fraud and spam by validating the sender’s identity.
How Does DKIM Work?
DKIM is based on a cryptographic signature which is generated using a pair of encryption keys. The sender’s Domain owner generates a private key, which is used to generate a digital signature attached to an email.
The receiver uses the sender’s public key to verify the authenticity of the signature. If the signature matches, the message is considered authentic and not altered.
Why DKIM is Important?

DKIM is an important tool for organizations to safeguard their emails and prevent their brand’s reputation from getting damaged. It also helps in avoiding spam filters from blocking legitimate emails

Conclusion
DKIM is an effective way of verifying the sender’s identity and ensuring that the message being sent is authentic and not altered in any way.
