It is EASY to lookup who owns(or is responsible) for a specific IP, and thus contact them about the spam, which you seem to indicate you DON'T bother doing.
I DON'T bother. Who has the time to waste? And if you do waste YOUR time to look it up, what are (lotto-like) chances that you'll get any response from the "contact"?
And, even better, what are the chances YOUR wasted time is going to change, improve?, anything anywhere for YOUR mail server and your users from the "contact"? zilch
If after contact they do nothing THEN block their range.
Right, that "lookup/try to contact/wait/then block" process scales right up to how many times per day? Who has the time? Who has the desire?
How many times have you followed your own advice?
That _dict filter I referred to has 1300 Class Cs and 14K IPs in it, you expect me to follow your process even just the 1300 times?
You say "the operator of the Class C has not policed his clients, and now he pays", but if he isn't notified about the spam then how can he police it?
His legit IP clients can't send mail to my MX (actually, there's very little chance of this ever occurring) That's MY kind of notify. It's THEIR problem, THEY fix it.
By not at least contacting the owner of the IP you are
... NOT wasting my time.
potentially allowing a spammer to continue operations
Not into my MX, he ain't. That's all I can control, my policies for the traffic through my MX.
and thus becoming an unwitting accomplice.
What he does to other MXs is his business and their problem, not mine.
He's spams me and I'm supposed to get "involved", according to you?
Why not take your logic one step further and block ALL internet traffic when you receive spam?
That's not my logic, obviously. But since it's your idea, you try it and tell us how it works.
