For nearly a month now I have been unable to access my Yandex account via Thunderbird (current version 115.6.0) on IMAP.
Before mid-February the same problem would occur intermittently and correct itself after a few days, so to begin with I thought nothing of it. However it persists.
I can still access Yandex webmail without any trouble, and all my other e-mail accounts are functioning normally, including via IMAP.
I used Bleachbit to give T'bird a good scour out but that didn't help.
Has anyone else had a similar experience?
My guts tell me that the problem is at the Yandex end. Maybe it's something to do with the war?
