DKIM can verify that the message content and attachments have not been modified since the original sender signed the message.
False
True
DKIM ensures that the message content and attachments are the same as when they were originally signed by the sender's domain. It does this by utilizing a cryptographic signature that is validated against the corresponding public key published in the sender's DNS records. If the message has been altered in transit, the cryptographic validation will fail. Thus, DKIM provides a method to check the integrity and authenticity of the message. However, DKIM alone does not prevent all forms of email spoofing and needs to be part of a larger set of email authentication methods including SPF and DMARC.
