[Dovecot] Errors after install with non-standard prefix

[Dmitry Samersoff]

Hi Everyone,

I'm new in dovecot - so first at all, thank you for amazing work.
I'd flicked through dovecot code and it's very accurate.

I'm trying to use dovecot with a little bit non-standard configuration:
dovecot installed under /my_path/dovecot, all users has the same home 
directory  /my_path/var/mail and have to access all mailboxes/folders 
located there.

But I have troubles with it:

Right after start dovecot start spamming log with

Error: dict: dict client: Broken handshake

besides of GB's of lines above I have:

Error: imap-login: Timeout waiting for handshake from auth server. my 
pid=18493, input bytes=0

And of course nothing works.

Thank you!
