Now, from your logs, just how much legitimate mail do you get that comes 
from an IP without PTR RR, and how much is that expressed as a 
percentage of legitimate incoming mail to your lists?  How much is that 
as a percentage of spam inbound to your list [to be fair, let's make it 
"spam that would not have been stopped by your other filters]?

btw, i did give you a cursory answer to this.  and i asked if you
would provide some data.

randy, waiting
