preline(1)                User Commands                preline(1)



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.
