What is a DKIM selector and how is it chosen?

  • The selector is chosen by your sending system or ESP. Each provider uses its own naming conventions.
  • You publish the public key at:
  • selector.domain.com
  • under the path:
  • selector.\_domainkey.domain.com
  • It is like telling the harbor inspector which drawer in the registry contains the official seal.
