About DKIM Records
DomainKeys Identified Mail (DKIM) is an email authentication method that allows the receiver to check that an email was indeed sent and authorized by the owner of the sending domain.
Key DKIM components:
- Selector: A string that helps locate the DKIM record in DNS
- Public Key: Used to verify the digital signature in email headers
- Private Key: Used by the sending server to sign outgoing emails
- Key Type: Usually RSA, determines the encryption algorithm
- Key Size: Larger keys (2048+ bits) provide better security
