Why did exim4 stop accepting mail?

Question

Debian

I set up a mail server on VPSk so that letters would not go to spam on Google. (Or rather, they were not accepted by Google at all, even to spam)
And tuned up to the point that the server stopped receiving mail
Sends now everything is ok
But now
debian7 * 64 does not accept any letters exim -bP
output

And what's in the logs? Or are we offered a competition for remote mental reading of your logs?
