What does a valid DKIM TXT record look like?

DKIM TXT records typically follow a specific syntax to work correctly. A valid record should:

• Start with one of these required tags:
  • v=DKIM1 - Version tag (required)
  • k=rsa - Key type (typically RSA)
  • p= - Public key (required, in base64)
• Optional tags may include:
  • t= - Flags for testing mode
  • o= - Oversigning options
