   Advanced setup

   Yandex Cloud Postbox will prepare keys and DNS records for you to add to your DNS provider. For more information, see DKIM signature.

   1. Generate a key to create a DKIM signature in the terminal on your local computer using this OpenSSL command:

      openssl genrsa -out privatekey.pem 2048
      

      The private key will be saved in the privatekey.pem file in the current directory.

      Yandex Cloud Postbox supports 1,024-bit and 2,048-bit keys.

      Note

      Some DNS providers impose length limitations on TXT records. If you encounter such an issue, use a 1024-bit key.

   2. In the Selector field, specify a selector, e.g., postbox. This selector should be used in one resource record only: the one you create when you pass the domain ownership check.

   3. In the Private key field, copy the contents of the privatekey.pem file.

7. Optionally, restrict the list of senders.

8. Optionally, configure logging.

9. Click Create address.

To send emails, pass a domain ownership check.
