In any case, the IETF config for TMDA is a white list only, as
far as I know. All known subscribers to IETF lists are automaticaly
white listed, and anyone else has to respond once to a challenge
to become white listed. Mail from non-white listed senders
goes into manual moderation. That's all. Not perfect, but it
stops a heck of a lot of spam.
