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.
