4. effects of DNS caching. if a host is removed from a blacklist it

designed to facilitate that.
The use of the term "SHOULD" here has legal implications - since many of
these hosts were put into the BL's by Address Spoofing they were in fact
NOT where the offensive SPAM was coming from and so placing those hosts
there when the real issue is the refusal of the EMAIL Admin to do proper
Header Filtration and Validation creates a direct liability.
I'm sorry to jump in once more. The paragraph above is simply incorrect.
A DNSBL that would be fooled by "address spoofing" would not provide
much value. What do you mean by "address spoofing"? Falsified "From:"
lines?
