[Dovecot] Missing public folder

[komodo]

Hi

i am using dovecot 2.0.13 and i can't see public folder in my mail client. But what is strange, it 
was working after instalation, and i don't know when it dissapeared. Maybe after some upgrade ?

When i enable debug, then i can see in my log that folder exists and no errors. Please where should 
i find the problem ?

Thanks

Martin
