General instructions for setting up the MX record
The MX record points to the server that receives email for your domain. For the Yandex server to process your email, you need to create an MX record that specifies this server.
If you want the Yandex server to handle email addresses that you used before setting up the MX record, create the same addresses for the appropriate domain. You can also import mailboxes with the messages they contain.
If you delegated your domain to Yandex servers, the MX record will be set up automatically. You can view it and edit its parameters in the DNS editor in Yandex.Mail for Domain.
Log in to the control panel on your DNS hosting company's website.
Delete the existing MX records.
Create a new MX record with the following field values (the fields may be named differently in different control panels):
Value — “mx.yandex.net.”.
The dot is required at the end of the server name. In some control panels, the dot is assumed automatically. In this case, you don't need to add it.
Priority — 10.
If a priority of “10” is not allowed in the control panel, enter any other priority other than zero.
Subdomain name — “@”.
In some control panels, you need to enter the name of your domain instead of “@” (for example, “yourdomain.tld.”). If you are not able to set either “@” or the domain name, leave this field empty.
If this field isn't shown in the control panel, you don't have to set it.
Wait while the changes take effect in DNS. This process may take up to 72 hours.
