I don't know what you mean, are you talking about stats for your 
machine, or more globally?

I use postfix; the logwatch report tells me who's blocked.

I have other rules too:
ehlo <something>
Something has to be present, resolvable and not a simple name. Stops 
lots (and some, but not many legit senders, and they get warned by their 
server if it's working)

The sender's IP must resolve to a domain name.

Those rules probably stop more than the block lists.
