Some providers are listed on backscatterer,org,
They say they don't want to pay a criminal organisation for removal.
But after some investigation it don't seem malicious at all and mean you are sending NDR to the spammin sender.
Now i get conflicting information about the matter.
So my question is simpel, do i have to take www.backscatterer.org
serious or not.
Becouse now i cannot use "ip reputation in my spamfilter" becouse of it.
