So, it looks like the googlebox - whatever that is - is connecting and
immediately saying HELO and QUIT. Not much point in that, but it seems you
aren't losing inbound mail.
Do you force a delay on incoming connections? If so, you should exempt
friendly machines. If you don't force a delay, then there's a problem with
the googlebox. It should wait for a greeting.
