I can send emails via enableSsl="false" and 25 port. But it is not enought in case with own domain.
What is wrong or missing in this settings?
<system.net>
    <mailSettings>
      <smtp  deliveryMethod="Network" from="Name">
        <network  host="smtp.yandex.ru" port= "465 " enableSsl="true" userName="noreply@domain.com" password="***" />
      </smtp>
    </mailSettings>
  </system.net>
