Domain keys identified mail (DKIM) is a simple yet effective way to validate emails reducing fraud attacks. In the old times, how kings would send letters to each other with a stamp, and if the stamp was intact, it meant that the letter hasn’t been tempered. Just like a stamp, in the digitalised era, emails are signed by a DKIM checker.

  1. The message has not been tampered with.
  2. It originates from the given domain name.
