Do all of these things:

  1. If your mailing list is implemented as an alias named "list",
     have another alias named "owner-list" that point to the
     person you want to receive error messages.
  2. Send mail to the mailing list using the sendmail's -f flag
     to change sendmail's idea of the sender of the message.
  3. Insert a Sender and an Errors-To header into the message,
     both pointing to the person you want to receive error
     messages.

The sender has to be a trusted user or the -f argument has to
have a `!' in it for the -f flag to work.
