Yandex.Mail

Report on non-delivery to another (non-Yandex) address

Forwarding prohibited

If you have sent a message from your Yandex mailbox and received a non-delivery report that states the following: “Relay not permitted”, “Sorry, relaying denied from your location”, this means that forwarding is prohibited (the recipient's mail server doesn't recognize Yandex mail servers due to incorrect MX record configuration).

Try contacting the recipient or their mail service administration by another method and report the problem.

Note. If you use Yandex 360 for Business and send an email to your domain's mailbox, keep in mind that it may take up to 48 hours for the MX record to propagate. If 48 hours already passed, make sure that the settings match the recommendations given in the article on setting up the MX records.
