Argh! Challenge-Reponse systems are purest evil! I'm sure that anyone who
runs a reasonable sized mailing list will agree with me.

Use amavisd+SpamAssassin instead. It hooks into your mail server to run
all your incoming mail through a barrage of different tests and gives each
message a "spamminess rating" in the message headers. It can automatically
bounce or silently drop mail that reaches certain scores too.

Whatsmore if you install a virus checker like ClamAV, it will hook into
that too to add virus scanning of incoming messages too.

ClamAV, SpamAssassin and amavisd are all free and open source.
