Yeah, the weighting of dnsbls is a very very good feature. However for
whats it worth:

day     pconnect        sconnect        relayed
21      1586    570     304
22      1726    634     474
23      3642    1629    603
24      4111    1867    460
25      3927    1782    460
26      4544    2356    468

pconnect = connections to postscreen
sconnect = connections handed from postscreen to smtpd

the difference between p and s-connect is what postscreen blocked (or
timeout).

relayed=mails relayed to another mailserver (found clean)

the difference between sconnect and relayed is what other filters
blocked (or timeout)

That's on a currently low-volume mailgateway.
