Mail in which domains of the former QIP is still working?

Question

Email

After moving under the wing of Yandex https://yandex.ru/support/mail/qip.html , quite a lot of time has passed. Is there any information - do the old mailboxes work in all domains or some of the domains have already died in Bose?
