DKIM 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 achieves this by adding a digital signature, linked to a domain name, to each outgoing email message. The recipient system can verify this by looking up the sender's public key published in the DNS.
