Milter-greylist

> How do you intend to reset this counter? Will it increase forever?

Yes, that was my first idea, to get a complete summary. 
But thats maybe not a great idea. However, i though that the counter could change to a format like "1,234*10^6" after passing the million barrier so the string showed whouldn't been like 12345678912345395235 flushed

And then zeroed out then milter-greylist is restarted (like the first enhancement that i suggested ("slow-relay-tagging").

> What about something like flushed 1533/hour

Then I would prefer flushed 12335/day (then the date changes on the machine, and logged into syslog then recalculated)

But perhaps that could be made customazible like the options greylist/timeout. That you could choose between seconds, minutes, hours and days... 
(So you could make it match your greylist/timeout interval)

For example

flushidx 1d / 2h / 30m etc.
(or whatever you want to call it...)
