For what it is worth I consider challenge/response as spam if I see the
challenge in my mail box. I tend to prefilter those addresses which do
this to /dev/null, particularly if they come from a mailing list message.
I don't have time to respond to challenges from all and sundry. It is a
VERY broken method.
