     NAME
          preline - prepend lines to message

     SYNOPSIS
          in .qmailext:  | preline command

     DESCRIPTION
          preline feeds each incoming mail message through command.
          At the top of each message it inserts a UUCP-style From_
          line, a Return-Path line, and a Delivered-To line.

          preline is useful for procmail and ELM's filter, which do
          not understand the qmail-command environment variables.

     OPTIONS
          -d   Do not include the Delivered-To line. You should use
               this option when the recipient of the incoming mail
               message is actually under remote control, but was sent
               here through control/virtualdomains for manual routing.

          -f   Do not include the From_ line. You should use this
               option except for commands that create mbox files.

          -r   Do not include the Return-Path line.
