[Users] Cannot sync large IMAP folder

[Nick Koretsky]

Hi!

I added an IMAP account with folder that has ~25k messages to claws and
claws cant sync message list. What happens is when i enter the folder claws
start downloading message headers, its not fast (looking at progress i
think it would take 2-3 hours to get all headers) and its never finishes.
Sooner or later some network error occurs (idk why, looks like session time
limit on server side), sync is aborted. If i try to enter folder again
process restarts from scratch with the same result. Again and again. Is
this a bug in claws or am i missing some setting that causes claws not to
write imap cache on aborted sync?

error message in log is

** IMAP error on imap.yandex.ru: stream error
** IMAP connection broken

P.S. Claws interface is partially unresponsive while IMAP syncing, is this
normal? I cant read messages in other accounts while IMAP is syncing, but
they are delivered, an menus are accessible. I never used claws with IMAP
before, only with POP, is IMAP support in claws "not very good" and i
should look for another client for IMAP?
