[Dovecot] Dovecot immediate logout (imap4)

[Дмитрий Бригадиров]

I've experienced with automatic client logout (probably after IDLE
command sent by a client).

I simply run any imap4 client and get this in mail.log:

3 login attempts each after another. Any way client shows me the inbox
and I can manage mail just fine. However it disconnects every time
instead of using idle command (this I my guess).

Don't know the reason for such a strange situation. Thanks for any
help in advance.
By the way I can't get rawlog to work. It doesn't write any logs to
home directory.
