postfix PTR Lookup internals

Hello everybody!

I see following *maillog* records when new mail comes to server

connect from unknown [209.85.223.195]
client=unknown[209.85.223.195]

But that IP address is GMail IP and it has valid PTR-record which
points to *mail-io0-f195.google.com
<http://mail-io0-f195.google.com>* My main.cf is here
