roundcube mailbox

Please tell me how to make sure that the mailbox registered on the adminvps hosting, which can now be accessed only through hosting and roundcube, can be accessed through Yandex? Thanks. There are a lot of articles, I know, but I don't have the opportunity to test, the deadlines are burning, I really need to set it up right away.... Thanks...
