	I agree that it is a bit of a stretch, however, even though it
is not written as an "anti-spam" patent, it still incorporates a process
of "challenge and response" via email messages that somewhat resembles
the method used in C/R systems which are specifically intended to
prevent spam. 
	One might argue that sending email messages is a form of
"transaction." 
	Or, it might be that you would infringe on this patent if you
combined a C/R system with one of the "pay to send" or "postage stamp"
systems that have been proposed elsewhere. In that case, the transaction
would be paying for the postage.
	It is also possible that one might argue that since this process
of "challenge and response" (although not called that in this patent)
had been incorporated into a patent application whose predecessor was
filed as long ago as 1994, that establishes that the method of C/R was
"obvious" to one skilled in the art by the time that later C/R related
patent applications were being filed five, six or more years later.
	Also, at least one of the inventors on this patent has claimed
that he believes it *may* be relevant to spam...
