Those are statistics relating to scache performance. It tells you how many domains or addresses were able to be delivered via scache reuse. I.e. how many emails Postfix was able to send through an already open SMTP connection to a given host. Since all of your qmail hosts are configured identically, and should be able to relay mail bound for any destination on the internet, you should never see anything less than ~100% in those statistics, _unless_ there is some other kind of problem. If your qmail servers are rate limiting via any method, and Postfix is attempting to send 2000 emails per minute down that one SMTP connection, when qmail blocks individual deliveries for any reason, those scache failure statistics will increase. -- Stan
