I am sorry but this is problem at Yandex side, they are using completely weird system which is nearly impossible to implement correctly.
I have same problem with Yandex, so I assume this issue is still remains?!
We have added better support with Yandex in current 5th version, it solved some issues and users report less problems with using it, but at this moment we can’t do more than this.
When we will know how to fix this it will be of course added into release version as soon as possible.
thank for quick response, Jan.
I’ve just installed eM, I really liked it, cause it’s simple:), but for some reasons I have problems with sync of my yandex box. I have checked all settings, but unfortunately nothing helps.I can’t get any message from yandex to eM, while my gmail account synced fine.
these problems with Inbox are exactly how is Yandex’s wrong authentication servers shown to users
as I have written we need to wait until they will fix it or we find another workaround over this.
