RE: Threading the senderbase reputation needle

I think this discussion would be much better on the mailop list, but
the short answer here is "real mail servers have real, non-generic names
with matching forward/reverse DNS".
--------

That certainly is true, but if a "real mail server" that has real, non-generic names with matching forward/reverse DNS 
happens to be in the same /24 as a server that doesn't it is given a poor reputation by Senderbase since Senderbase 
cannot do simple RIR lookups to see the scope of that particular customer's network/impact.
