Domain ownership verification
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 records you need to add to your domain zone. You can add the records via your registrar or in Yandex Cloud DNS, if you have delegated your Yandex Cloud domain.
With the simple setup, Yandex Cloud Postbox automatically generates DKIM keys. The two CNAME records you need to add to your DNS provider are displayed under Email signature configuration (DKIM) on the address page.
Example of creating resource records in Yandex Cloud DNS
-
In the management console, select the folder containing the address and your domain zone.
If you do not have a public DNS zone yet, create one:
-
Go to Cloud Postbox.
-
Select the new address and open the Email signature configuration (DKIM) section.
-
For each of the two CNAME records, complete the following steps:
-
Go to Cloud DNS.
-
Select your domain zone.
-
Click Create record.
-
In the Type field, select
CNAME. -
Enter the record name from the Email signature configuration (DKIM) section on the address page into the Name field, omitting the domain.
Note
Other DNS services may require a full record name, including the domain.
-
In the Data field, paste the record value from the Email signature configuration (DKIM) section on the address page.
-
In the TTL (in seconds) field, specify the record lifetime.
-
Click Create.
-
-
Go to Cloud Postbox.
-
Select the address you created.
-
Wait for Yandex Cloud Postbox to verify the DKIM signature settings. If the records are correct, the verification status on the address page will change to
Success.
With the advanced setup, you need to manually generate the key for the DKIM signature. The Email signature configuration (DKIM) section on the address page displays a single TXT record you need to add to your DNS provider.
Example of creating resource records in Yandex Cloud DNS
-
In the management console, select the folder containing the address and your domain zone.
If you do not have a public DNS zone yet, create one:
-
Go to Cloud DNS.
-
Select your domain zone.
-
Click Create record.
-
In the Name field, specify the name portion generated when creating the address, omitting the domain in
<selector>._domainkeyformat, 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.. -
In the Type field, select
TXT. -
Paste the contents of the Value field under Email signature configuration (DKIM) 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"Note
Other DNS services may have different requirements for resource record formatting. For more information, refer to your DNS provider’s guides.
-
In the TTL (in seconds) field, specify the record lifetime.
-
Click Create.
-
Go to Cloud Postbox.
-
Select the address you created.
-
Wait for Yandex Cloud Postbox to verify the DKIM signature settings. If the record is correct, the verification status on the address page will change to
Success.
DNS server responses are cached, so you may experience delays when updating the resource record. If the verification status does not change within 24 hours, click Run verification.
