*chuckle*

I wouldn't go so far, since the spam that evoked it is far worse, but
I'm steadfastly opposed to challenge-response.

If you absolutely *must* do this thing, be prepared to get violent
responses and to lose mail from people that you'd really like to get
mail from.

Now that you're properly warned, I believe that there is a description
of how to integrate TMDA, a popular Python-based challenge-response
system, into Mailman in the Mailman FAQ wizard.  If not, I suppose
there would be one on the TMDA home page.
