Setting up a DMARC policy
To protect your domain from sender email spoofing and increase the security of your email communications, you need to set up a DMARC policy. Make sure your domain zone settings include the _dmarc.<domain>. TXT record. You can add a record with your registrar or in Yandex Cloud DNS if you have delegated your domain.
Example of creating a DMARC record in Cloud DNS
-
In the management console, select the folder containing the address and your domain zone.
-
Navigate to Cloud DNS.
-
Select your domain zone.
-
Click Create record.
-
In the Name field, specify
_dmarc.Note
For other DNS services, you may need to enter the full record name. The final record should be named
_dmarc.<domain>.. -
In the Type list, select
TXT. -
In the Data field, enter a valid DMARC policy value. Note that the record value must be enclosed in quotes, such as follows:
"v=DMARC1;p=none"This DMARC record means that if an email fails the DMARC check, the mail service will take no action, such as rejecting the email or classifying it as spam.
-
Click Create.
DNS server responses are cached, so you may experience delays when updating the resource record.
