There is a strong consensus that says the challenge-response spam filtering
creates more problems than it solves. However, I do understand that from the
perspective of the person paying for the service (who does not get any
spam), it looks like a good solution.

There is a good description of why it works badly if you're on a mailing
list:

Personally, I've never seen the challenges when I use the TFT list, but I
suspect Gmail is smart enough to treat them as junk.
