| TMDA has effectively reduced the amount of spam I receive from many
| hundreds per week (my personal high was 300 a day over the course
| of more than two weeks) to essentially zero.  TMDA relies on white
| lists and automated responses to mails from unknown senders.

  While this probably works to keep unwanted initial contacts out of
  your mailbox, e-mail works so well because it is a very convenient
  initial contact medium.  The threshold to making the first contact
  with a relative stranger is already high, and automated answer that
  requires manual intervention is worse than calling people you don't
  know and only getting their answering machine telling you that they
  screen their calls.  I hate answering marchines and don't use them,
  and I tend to hang up and try again later if I get one.  (For this
  reason, I really love SMS, which I also send before I call people
  to tell them what I'm going to call about and when.  This habit was
  picked up by a number of lawyers I know, who say it saves them and
  their clients a lot of time.)  I have to admit that I have received
  TMDA-style responses from people I have tried to communicate with
  and just found that it was not worth it.  This is a false negative
  that I think argues very strongly against TMDA-style solutions.  If
  something like this is necessary, it should be handled by the mail
  clients automatically and not involve human time at all.  I have
  not seen any attempt to do this, but would love to hear about it.

Act from reason, and failure makes you rethink and study harder.
Act from faith, and failure makes you blame someone and push harder.
