As for challenge/response schemes, they're fine for people who want to

directly, they wouldn't be so annoying.
That's a bit of a double-edge sword, since if you can automate them, the
spammers can automate them.
On the other hand, I think the odds are low that a spammer can maintain a
return address that actually functions long enough to reply to a
significant number of whitelist confirmations. Not to mention that the
reward for accomplishing such is getting exactly one bit of spam through
to a user; once it arrives, the user is likely to blacklist the newly
whitelisted address.
