I received a non-delivery message

If the letter cannot be delivered to the recipient, mail server may respond with a non-delivery report. Some types of reports and solutions to related problems are described below.

Callout verification failed

This error occurs when the mail service for a domain is active on the server of your hosting provider or registrar. If a letter is sent to a recipient who uses the same company's postal service, it will be sent to local server.

Checking the existence of the sender is sometimes used by the receiving server to protect against spam. The server that receives the letter from the new server sends an empty letter to the return address to check if the sender exists. Since empty letters of this kind are sometimes sent with high frequency, this can be considered a denial of service attack (DoS attack). Additionally, when sending a test message, problems may occur. unexpected errors.

Yandex.Mail uses Sender Policy Framework entries to maintain a list of nodes that are allowed to send email on behalf of Yandex.Mail addresses. This makes it difficult to spoof the sender's address.

From time to time, users complain that they do not receive letters to Yandex mail. Why might this happen? How to deal with this problem? Is everything really as dangerous as it seems at first glance? All this will be answered further. In fact, there can be a lot of problems. But there is clearly no need to panic. Most situations are resolved without much difficulty.

Network failure

Why don't I receive letters to Yandex mail? The whole thing may lie in the most ordinary system failure of this service. This does not depend on the user. Occurs due to overload of the main server or during an update.

If the network fails, some users may receive emails, but others may not. There are also problems sending messages. There is no need to be afraid. It's enough just to wait a little. As soon as network failures and problems are corrected, mail will begin to work at full capacity.

Spam

But this is not the most common problem. Are your emails not coming to Yandex? Most often, the messages actually reach the user's mailbox. All letters are simply placed not in the “Inbox”, but in the “Spam” folder.

If you are expecting to receive a message, but it does not arrive for a long time, it is recommended to check the specified folder. Most likely, this is where the lost letter will be. A very common occurrence related to email settings and filters.

So it is advisable to check your Spam folder in advance. As practice shows, half of users stop complaining about the problem that arises. But these are not all the options for the development of events. There is another reason why letters do not arrive at Yandex mail.

Lock

It is likely that messages from certain domains or addresses will not reach the recipient. Moreover, it is not necessary to have mail on Yandex; the problem can happen with any hosting. The reason lies in automatic settings services that include blocking certain emails.

IN in this case It is recommended to write to Yandex technical support. Although many users advise simply setting up an email account on a different hosting. Unblocking is not easy. But you can try to resolve the situation on your own. Are you not receiving emails from Yandex from GMail? Just try to work a little with the filters. Maybe it will be possible to remove the blocking without much difficulty.

Working with filters

If letters from a user are placed in the Spam folder or are not received by the user, it is recommended to enable the security filter settings in Yandex. How to do it?

Just follow the instructions:

  1. Log in via email. Next go to "Settings".
  2. Select "Mail Processing Rules" from the menu that appears.
  3. Go to the "White List" section and enter the required sender's address in the appropriate window.
  4. Click on "Add".

From now on, contacts from the White List will no longer be placed in the Spam folder. And they won’t be recognized as prohibited either. It is clear what to do if letters do not arrive at Yandex mail.

Overcrowding

But that is not all. Sometimes the reason that letters do not arrive at one or another email address is simply overcrowding with data. Each service has its own limit of incoming and outgoing documents. It is likely that it is exhausted.

It’s enough to simply clear your mail of accumulated letters. After this, you won’t have to wonder why letters don’t arrive at Yandex mail.
