Domain ownership verification

Written by

Updated at March 3, 2025

To send emails, confirm domain ownership. After creating an address, DKIM signature settings will be generated on its page. Specify them as the values of the resource record you need to add to your domain zone. You can add a record with your registrar or in Yandex Cloud DNS if you have delegated your domain.

Example of creating a resource record in Cloud DNS

Management console
  1. In the management console, select the folder containing the address and your domain zone.

  2. Select Cloud DNS.

  3. Select your domain zone.

  4. Click Create record.

  5. In the Name field, specify the name portion generated when creating the address, omitting the domain in <selector>._domainkey format, e.g., postbox._domainkey.

    Note

    For other DNS services, you may need to copy the entire record. The final record must look like this: <selector>._domainkey.<domain>., e.g., postbox._domainkey.example.com..

  6. In the Type list, select TXT.

  7. Copy the contents of the Value field from the Signature verification section and paste it into the Data field. Note that the record value must be enclosed in quotes, for example:

    "v=DKIM1;h=sha256;k=rsa;p=M1B...aCA8"
    
  8. Click Create.

  9. Go to Cloud Postbox.

  10. Select the address you created.

  11. Click Verify address. If the record is correct, the verification status on the address page will change to Success.

DNS server responses are cached, so delays may occur when updating a resource record.
