Get information about DKIM

DKIM () is a way to sign email messages so that the sender's domain can be identified.

This request is used for getting:
  • information about why outgoing messages are not signed (for example, the DNS settings do not have a record with the public DKIM key).
  • a public DKIM key, in order to manually add it to DNS settings.
  • a private DKIM key, in order to configure the message signature on your own mail server.
