Um, no.

Challenge goes back to the forged e-mail address.  The only one that knows 
your 'email is live' is the innocent bystander you just inconvenienced.  They 
may, perhaps, tell spamcop and then your mail server ends up on their RBL and 
your mail server operator is NOT happy with you at all.

C/R is not only evil it can have negative consequences for those that choose 
to use it.
