TitanKey claims that this tiny modification to normal C/R
procedure results in a "massive" improvement in the utility of challenge
and response systems since spamming software won't be able to
distinguish between real "user unknown" errors and the fake ones issued
by TitanKey. Since spamming programs typically respond to a permanent
SMTP error by removing that email address from the list of active
emails,

you shouldn't ever receive more than one email from any one spammer...
The difference between theory and practice is that in theory, the
theory works, in practice it doesn't. Check out the web page at...
http://www.spamresource.com/nadine/ for a well documented example of
the falsehood of that claim. TitanKey seem to be a bunch of clueless
noobs who don't have a clue about *CURRENT* spammer behaviour. And if
their protocol is ever widely adopted, spammers will have more reason to
pound away at servers that claim no-such-user.

Are they claiming a patent on lying ? That'll be easy to toss out in
court. The US can bring forth Bill Clinton, and Canada can bring forth
Jean Chretien and claim "prior art".

Email users are divided into two classes;
1) Those who have effective spam-blocking
2) Those who wish they did
