I have no comment on your proposed solution. I can however point out the
statistics that I see on my own spam traps.
It seems that 90%+ of the spam coming from DNSWL listed hosts is Yahoo
and Hotmail which are listed as DNSWL_NONE. Meanwhile very few spam
comes from gmail.com. Apparently DNSWL agrees because they give
gmail.com's outgoing MTA's a "LOW" ranking which is pretty good for a
freemail provider. Google is doing something right in outgoing spam
prevention.

Exactly.
If Google can manage to do a pretty good job then it just tells me
Microsoft and Yahoo don't care. I've long since stopped caring too and
have scored them in SpamAssassin - the only way their mail gets through
now is if the sender address is whitelisted or they score some negative
points (e.g, Bayes) to get them back below my threshold. These providers
are NOT too big to block and the sooner we all start realising that the
sooner they might start to care about their reputations and stop
emitting huge volumes of spam.
Personally I think it's about time FROM_HOTMAIL and FROM_YAHOO became
high scoring stock rules in SpamAssassin. A score of 3 points might be a
reasonable starting point.
I'd agree, but users wont rebel against Yahoo unless they begin to see
actual bounces to their sent mail.
I do agree that we should have FROM_HOTMAIL and FROM_YAHOO so we can
independently decide how to treat their mail separate from typical FREEMAIL.
