Same username on same mail domain?

Question

Yandex

I periodically receive someone else's mail. All sorts of distributions. Even bank statements (I wrote to the Central Bank of the Russian Federation, but they sent me there). From a namesake. Perhaps a person with an error indicates his address - I thought. My mail is hyphenated, and he has a dot between his first and last name, but he makes a mistake and also writes a hyphen. I tried to write to the address with a period, but the letters came to me. Yandex explained that for their server, the dot and the hyphen are the same, that is, there is no difference. It's the same mail. Accordingly, this is not the error.

The other day I received another letter. But from a living person. The addressee indicated two mails, one of them was mine, the second - the other, working, someone else's. No one answered the worker, so I called the sender at the cell phone number (there were contact details below) and found out the phone number of my namesake.

I already triumphed, they say, finally the unfortunate one will stop squinting and spreading his personal life. Fail. The person on the other end of the phone laughed a lot after my story, but no, firstly, it's not him who sends mail to me, and secondly, he has the same e-mail address... WTF?! He told me that he was very surprised when yesterday he received a letter from himself with questions about banks and other things.

1. Yes, we have the same mail.
2. Both have it for 15 years.
3. We do not receive each other's letters.

What was it and what should I write about in Yandex?This "privacy" bothers me, so I want something done about it. And there is a suspicion that this is some kind of completely fake bug that is not unique and specifically wipes its feet on the secret of personal correspondence. And the person who "by mistake" indicates my address is not mistaken, but somewhere on the server Yandex cant.

PS My versions:
1. A person does not have a hyphen, but a dash in the mail (but it seems that this is not possible).
2. A person does not have a hyphen, but a minus in the mail (but this, it seems, is also impossible).
3. Depending on the keyboard layout, a different Unicode character is used (for example, Russian minus/hyphen differs from English in code).
4. No more versions...

Answer 1

Have you checked by sending letters from mail to Yandex?
Send all the same options from your Google account, and if possible, from other addresses. The result may be different.
By the way, this material is a finished article on Habr. There, the audience is an order of magnitude larger, and the scope of competencies is wider. And Yandex will definitely respond there.

Answer 2

Open the technical header of the emails ( RFC-822 e-mail headers ). Find the recipient's real address. Set up a filter for forwarding other people's emails.

Answer 3

You need to understand that email is generally a sieve. Never use email for anything important. NEVER.
I made an email on my domain at Yandex. After some time, I changed all DNS records and switched to another provider. I don't have any record related to Yandex. But letters still come to Yandex just fine! The email technology itself is miserable. I'm silent what the hell to raise the mail server myself.

Answer 4

Yandex explained that for their server, a dot and a hyphen are the same

at the dawn of Gmail, he bet beer, arguing that the dot in the address to the dog cannot be ignored,
I was smart, the admin, and I read the RFC, yeah
hmda
but there are no miracles, smart people are smart for that , (although numbers are more interesting ) .
You just need to state the facts to Yandex by doing a few experiments, better with scripts:
1) send 5-10 letters to your address with a hyphen
2) to yours - replace the hyphen with a dot
3) go through domain aliases, etc.
that is, you need to find a pattern , and then ask for help from your counterparts by headings, etc.

Answer 5

On logins with a hyphen, a dot, an underscore - I have not noticed such a problem in the 20 years of the existence of the boxes.
But on their domain - yes, they constantly send left mail, making a mistake with the letter after @. There the probability is higher, because everything before @ comes to me.
