Mail in .rf domains

Question

Domain name market

Say what you like, but domains in the zone.rf are gaining popularity and conquering the market. By the way, convenient! I called Marya Ivanovna from the accounting department and instead of "Jay, En, Al, DoubleVE ..." say "work dot rf."
So all the advantages are obvious, but what about the mail? Does anyone have experience using emails in Cyrillic?
On nic.ru in the forum, people unsubscribe that everything is like a bundle and even works.

Answer 1

Well, we use corporate mail on Yandex for this, but even there, when creating, it is written

Many major mail services and popular mail programs do not support sending emails to mailboxes of domains in the .рф zone. Delivery of letters to addresses in the .рф zone is guaranteed only if they are sent from the Yandex.Mail web interface.
In addition, mailbox names (the part before the "@" symbol) cannot contain Cyrillic characters - this is prohibited by the rules of existing mail protocols. For example, you will not be able to create a mailbox like [email protected]
