[Dovecot] New messages notification - (IMAP PUSH?)

[Proskurin Kirill]

Hello all.

I have strange problem.
As I understand IMAP use server2client command to tell what new email is 
arrived.

So - all was good, but few weeks ago I notice what my thunderbird not 
show new messages. I think it was local problem(I switch distro what 
day) but soon my email clients what uses mostly Outlook-2007-SP1  start 
to confirm this problem.

What can it be and how can I fix it?
I use Dovecot on FreeBSD-7.1

dovecot-1.1.11

dovecot-sieve-1.1.6
