Support service - Yandex ID. Help
https://yandex.com/support/id/feedback.htmlMailboxes on the domain are managed by the domain owner, so Yandex support cannot help you restore passwords to them. If you have a tut.by, e-mail.ru, or e1.ru mailbox, you can only change your password in your account area: tut.by account, e-mail.ru account, e1.ru account. If you are a domain administrator, contact Yandex.Connect support.
