The SPF record helps reduce the risk of email sent from an address on your domain being put in the recipient's spam folder. To configure the SPF record, create a TXT record with a list of servers that send email from your domain.
If you delegated your domain to Yandex servers, the SPF record is configured automatically. You can view and edit it in the Yandex.Connect DNS editor.
General instructions for configuring SPF records
Log in to your DNS hosting company's control panel.
Create a TXT record with the value
If you want to send email from non-Yandex servers as well, specify the additional servers in the format:
v=spf1 ip4:<IP-1> ip4:<IP-2> include:_spf.yandex.net ~all
Here <IP-1> and <IP-2> are the IP addresses of your additional servers.
Enter the @ symbol in the field for entering the name or host, if there is such a field.
In some control panels, you need to enter the name of your domain instead of the @ symbol (for example, “yourdomain.com”). If you aren't able to enter either @ or the domain name, leave this field empty.
Wait for the changes to take effect in the DNS (this may take up to 72 hours).
