docs: // SetIdentityDkimEnabled API operation for Amazon Simple Email Service.
  //
  // Enables or disables Easy DKIM signing of email sent from an identity:
  //
  //    * If Easy DKIM signing is enabled for a domain name identity (such as
  //    example.com), then Amazon SES will DKIM-sign all email sent by addresses
  //    under that domain name (for example, user@example.com).
  //
  //    * If Easy DKIM signing is enabled for an email address, then Amazon SES
  //    will DKIM-sign all email sent by that email address.
  //
  // For email addresses (for example, user@example.com), you can only enable
  // Easy DKIM signing if the corresponding domain (in this case, example.com)
  // has been set up for Easy DKIM using the AWS Console or the VerifyDomainDkim
  // operation.
  //
  // You can execute this operation no more than once per second.
  //
  // For more information about Easy DKIM signing, go to the Amazon SES Developer
  // Guide (http://docs.aws.amazon.com/ses/latest/DeveloperGuide/easy-dkim.html).
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.

  // See the AWS API reference guide for Amazon Simple Email Service's
