If I can borrow this thread...

I'm curious what people think about challenge/response (C/R) for spam 
control.  I can see it being fairly successful, but I can also see it 
cutting down or eliminating real email from people you don't hear from 
often enough to have whitelisted.  What are the thoughts of people on 
this subject?

I'm asking because I've decided to start ignoring C/R types email 
totally, and I'd like to know if I'm going down a wrong road because C/R 
is the wave of the future (I don't think so but I am asking because I 
could be mistaken).  I understand people use it for spam control, but it 
so inconveniences me, I've decided that they probably didn't really want 
my email to begin with.

Nothing against the person who wrote the snippet I quoted, or anyone 
else here for that matter; but reading that reminded me of my question. :-)
