where did you see that? we apparently don't reads the same newspapers:)

Please either give a reference to a serious study with serious numbers
or stop this. otherwise everybody can speculate. let me try some:

- The US state dept will bomb all korean spammers
- Many countries will prohibit email
- smtp will be replaced by P2P
- postfix will be rewritten in .Net
....

anyway, there's no point in looking for errors, because it is not easy
to determine whether the error is caused by bad practice from the
sender, by transient problems, or by the rcpt side. you can't punish the
sender because of an error, otheriwse, you're subject to DoS of your users.

Any proposition to solve the spam problem that cannot be described
without citing the word "ISP" (or MSP, or the like) is a loss of time
and resources.
