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 does not recognize Yandex.Mail mail servers because the MX record is incorrect).

Try contacting the recipient or his/her mail service administration by another method and report the problem.

Note. If you use Yandex.Mail for Domain and send an email to your domain's mailbox, note 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.
