Since these folks don't have the sense or manners to change the subject
line when they change the subject, here's the original post:

Toronto Star - August 4, 2003
So what does [Kevin] Mitnick, former
hacker supremo, use to guard against
spam? "I use Spam Arrest," he told
The Guardian. "Any legitimate person
who wants to send me a message has to
jump through hoops before they can be
added to my opt-in list." Read

This is a little more information about him that I
added shortly after the original post.

Kevin Mitnick is also one of the world's foremost
computer security experts, which is one of the
reasons he uses challenge-responses:

People that send viruses and worms and such around
the internet, deliberately or unwittingly, do
not use their real email address or would not know
what mail the challenge-response was referring to if
the did receive one as the result of their address
being forged or used by a malicious program they did
not even know they were running.

They certainly would not have a copy to re-send to
the person whose challenge-response they recieved.

Therefore, his program just dumps the virus/worms
and they are never opened or even saved in memory.

This is very good protection against email-born
malicious programs.
