and forge anyway, given that the spammer pays microsoft
enough $$$ (see hotmail, where
one can, as a spammer, pay microsoft to get whitelisted in
their spam checkers).
This is patently false. You just skimmed that headline on Slashdot,
didn't you?
Microsoft is using IronPort's bonded sender program. A company puts up a
cash bond with IronPort saying "I will not spam". The amount is set by
IronPort based on past behavior, reputation, etc. If the sender spams,
the bond money is forfeited *to IronPort*. No money goes to Microsoft at
all. You cannot "pay to spam".
Microsoft is whitelisting those bonded senders in Hotmail, presumably
because MS thinks there should be an option in place for responisble
email marketers, newsletter providers, and organizations that want to be
sure every message gets through. (I do not necessarily agree with this
model, but Hotmail is MS's turf, so they can do what they want).
As they say on slashdot: RTFA before you post.
