preline1
Prepend lines to message
Usage
in {.qmailext: | preline
command}
Overview
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

Delivered-Toline. You should use this option when the recipient of the incoming mail message is actually under remote control, but was sent here throughcontrol/virtualdomainsfor manual routing.
-
-f -
Do not include the
From_line. You should use this option except for commands that create mbox files.
