Issue description

When creating an MX record, you see this error: Incorrect format: expected an integer.

The Incorrect format: expected an integer error indicates that when creating an MX record, one of its fields includes text instead of a number.

The MX record consists of two parts:

PREFERENCE: A 16-bit integer that specifies the host priority. The lower the value, the higher the host preference.
EXCHANGE: The FQDN of the host that processes emails in the specified zone. This field value must point to an A or AAAA record.

Alert

In the Value field, you need to specify a number (record priority) followed by text. For example, 10 mx.yandex.net.

When creating a request, please attach a screenshot of the record settings.
