Autoregistration Yandex mail. How to win?

Question

Yandex

Who faced or works with yandex?
The point is this.
You need about 2000 mailboxes for yandex. For handling correspondence, nothing more than natural.
- we can not help but create such accounts and buy too.
How we work with mailboxes: Logging in and reading letters through a regular browser, using the imacros script
1) Purchase - all purchased mailboxes - are blocked by Yandex on the first visit. We bought all sorts of activated ones, with SMS, in general, everything that is.
2) We tried to register ourselves (from a dedicated ip), wrote a script through the browser, registers, enough for 1 visit, then blocks. requires to change the number and specify the number
/// there is an ambush - SMS does not send for some reason (error: it was not possible to send SMS for confirmation)
without a number, not like ..
Even if by some miracle we bind the number, will it continue after some time to ask for confirmation by SMS there or change the password via SMS, use the SMS service option?
People work with a large volume of boxes with 1 ip - tell me what solutions - you use blocking exceptions ..

Answer 1

And what prevents you from using the Yandex service "mail for domain" and pushing as many mailboxes as you like there?

Answer 2

I would like to hear the advice of those who work professionally with a lot of yandex accounts .. Is there anyone? since within the framework of the task all the intricacies will still lead to the task described by me ..
