on 4) for information there is this blocking list:

the whole country of Fiji.
That shouldn't be a problem if you don't communicate with people from Fiji. :-)
Also as a note, I think dealing with high volume mail sender is not
the issue, they are known, we know their technics, etc... it is more
to deal with the long tail of little companies, organisations, small
ISPs, etc..
Some receivers may view these small organizations as statistically
insignificant. These small organizations generally adopt antispam
policies without analyzing whether such policies can have a negative
impact on them in future.

White-listing based upon a domain would be dangerous without also

There are companies currently providing this service, particularly
needed where spam remains largely unmanaged.
The question was whether it is important to note where the message
came from. I take it that your answer is yes.
The algorithm can remain oblivious to who owns the SMTP client. It
determines whether a conversation was observed, while also allowing
also users to submit corrections.
That only works as long as the two end-points for the conversation
are static. Such a constraint is only acceptable to users until they
move around and experience a communication failure.
