hi!

    i started (wasn't my intention) the thread in clamav. I like (and 
use) ASK, and i think the same as you about the bounces ratio, but i 
don't get the meaning of this one:

   anyway, one point raised in clamav was quite relevant: spam with 
spamcop-spamtrap accounts forged sender. What would result in inclusion 
in spamcop blacklist. It didn't happen in here, but i think it's just a 
matter of time. So, i was thinking: is it possible to send challenges 
only on certain emails? For instance, only those that are below certain 
SpamAssassin score? I'm using ASK 2.4


    best regards,
