TMDA is good, but not good enough in my opinion. I'm currently
developing something similar that fits into my setup and also would be
able to act as a front end for mailinglists, individually tuned for each
and every list or need. That however is far from finished and well

thus not is on the whitelist. It will only hit that person once and
never again and it would (if we take my suggestion about delimiters in
account) even take care of one time email-adresses or list specific

I didn't say, my suggestion was 100% tight. I just said it would take
most of it.
