The % figure will vary a great deal, depending on which spammers
got your address first, and from which source. When I first
blocked those IP ranges, it cut spam by about 90%. Even though
most of the UCE *senders* live in the U.S., they send most of
their spam through badly-configured open mail relays in Asia and
Eastern Europe, etc. -- where I can't contact an ISP to get the
account suspended. Most U.S. ISPs don't tolerate spammers, and
they will respond to complaints. It's almost impossible to get
any response from Internet providers on RIPE, APNIC, etc.
If U.S. lawmakers had the honesty & courage to stop the U.S.
spammers, wordwide spam would be reduced by 90%.

That's one good approach. It's a good start.
By keeping STRICT compliance with my own rules of email address
management, I only receive about one spam email per week, average.
Another user on the same mail server, who keeps the same address
indefinitely, and just relies on the usual Postfix anti-UCE methods
plus his mail client spam filters, receives about 12 per day.
None of that would be necessary, if the email system wasn't so
badly conceived to begin with, if so many mail servers weren't
incorrectly configured, and if so many application progs weren't
so sloppy in their interpretation of the standards, which are
sloppy to begin with.
This is one problem we can't blame on Micro$oft. The Unix world
created this mess, and Linux inherited it. Who will fix it?
