Is The Bat crooked or is the problem deeper?

Question

Email

Good day, dear connoisseurs.
There are 15+ mailboxes from users in the mail for the domain from Yandex. Teams are made in it by type:
direktor - 5 people
, zakaz - 10 people
and office - everything is there.
Everyone has The Bat. It happens that you write to the mail [email protected] and it ends up in the office folder. Mail we walk our lives.
The question is: is The bat doing this with brains or is there a problem somewhere at the Yandex level?
