   4 # This is a sample script for demonstrating how to handle unknown users in
   5 # a more friendly way than just returning a "user unknown" error. It can
   6 # be called from a pipe transport set up like this:
   7
   8 # unknownuser_pipe:
   9 #   driver = pipe;
  10 #   command = "/opt/exim/util/unknownuser.sh",
  11 #   ignore_status,
  12 #   return_output,
  13 #   user = nobody
  14
  15 # which is specified by a smartuser director set up like this:
  16
  17 # unknownuser:
  18 #   transport = unknownuser_pipe,
  19 #   no_verify,
  20 #   driver = smartuser;
  21
  22 # Any output generated by this script is then returned to the sender of
  23 # the message. You can run any commands you like at this point, for example,
  24 # to attempt fuzzy matches on the local part of the address. Here we just
  25 # give a bland message, demonstrating the availability of the variables
  26 # $LOCAL_PART and $DOMAIN.

  29 "$LOCAL_PART" is not a known user mailbox in the domain "$DOMAIN".
