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