I agree that the spammers main vulnerability
is their need for anonymity. ( In fact several
of the largest well known spammers have been
harassed and even received death threats. )

I disagree that signatures are needed. Instead
start a compaign. Provide software ( for free )
to people that scans saved mail messages and
1) Checks if the source is an open relay
( generally by checking for particular relay
software ). It then looks up the ISP of the
relay and notifies them.
2) Parse the header and lookup the ISP.

We then need the cooperation of the ISPs,
but most ISPs are being hurt enough by ISPs
that they will be willing. Any ISP that doesn't
cooperate will be blacklisted.

There will be people hurt by this: the idiots
that let their machine get hacked, or install
AnlaogX proxy or some other open relay software.

But these idiots are making a mess of the net
by letting their machines be used by hackers and
spammers. It's time to stop coddling people and
make them pay for their stupidity.
