I guess I didn't explain myself clearly in the OP.
The count is for the mentioned time period.
I was getting no less than 1000/day to 7 addresses that I had directed into one email box over that 6 year period.
I was getting 200-500/month to non-existent addresses. So that total is over a two year period.
Since the recent botnet take downs, the daily count has dropped significantly. Now, since I recently started reporting 419 addresses from an email on the same domain, those abandoned addresses are being removed from spammers address lists. I was getting 25-30 419 spams per day, now I get maybe 2 per day. I'll have to wait a little while longer to see if the other types of spam start to drop off too.
