tmda challenge-response is not an effective solution against spam. There
are a few reasons:

* When a spammer sends you a mail, the autoresponse you send out will
  effectively spam other people. You're saying "I don't like to be
  spammed, so I'm spamming you instead". That's annoying, at best.
* Many people (me included, but there are certainly more) do not bother
  to jump through hoops for the amazing privilege to communicate with a
  complete stranger. Requiring people to do so will indeed get you rid
  of all your spam, but it will include a fair amount of legitimate
  mail, too.
