   4 I wanted to be able to preserve the envelope contents (except for the return
   5 path when I'm feeling paranoid about error handling).
   6
   7 Feel free to add this to the examples -- someone else might find it useful. I
   8 also have a complete configuration which I have been recommending to other
   9 people in Cambridge (although it could work elsewhere with tweaks) at
  10 http://www-uxsup.csx.cam.ac.uk/~fanf2/conf4.satellite.

  12 # Deliver a duplicate of some proportion of all messages to a special
  13 # machine specified in the file /MAIL_TAP_HOST, if it exists. The
  14 # probability of sending a message is the reciprocal of the second
  15 # number in the hash part of the condition. The address data is used
  16 # to prevent redirected addresses from being tapped twice. The
  17 # originating host and sender are recorded in extra headers. If the
  18 # delivery fails the bounce goes to a rubbish bin (although this means
  19 # that the traffic seen by the tap is not quite the same as the
  20 # traffic seen here).
