Nested folder structure support with Yandex

For Yandex imap, there is no support for nested folder structure.

Real folder structure

+A
|___B
|___C
|___D

Appears in the program

+A

  • A | B
  • A | C
  • A | D

As I understand it, yandex uses the piple line " | " as a separator and the program cannot parse this
