NAME
qmail-inject - preprocess and send a mail message
SYNOPSIS
qmail-inject [ -nNaAhH ] [ -fsender ] [ recip ... ]
DESCRIPTION
qmail-inject reads a mail message from its standard input,
adds appropriate information to the message header, and
invokes qmail-queue to send the message to one or more
recipients.
See qmail-header(5) for information on how qmail-inject
rewrites header fields.
qmail-inject normally exits 0. It exits 100 if it was
invoked improperly or if there is a severe syntax error in
the message. It exits 111 for temporary errors.
ENVIRONMENT VARIABLES
For the convenience of users who do not run qmail-inject
directly, qmail-inject takes many options through
environment variables.
The user name in the From header field is set by QMAILUSER,
MAILUSER, USER, or LOGNAME, whichever comes first.
The host name is normally set by the defaulthost control but
can be overridden with QMAILHOST or MAILHOST.
The personal name is QMAILNAME, MAILNAME, or NAME.
The default envelope sender address is the same as the
default From address, but it can be overridden with
QMAILSUSER and QMAILSHOST. It may also be modified by the r
and m letters described below. Bounces will be sent to this
address.
If QMAILMFTFILE is set, qmail-inject reads a list of mailing
list addresses, one per line, from that file. If To+Cc
includes one of those addresses (without regard to case),
qmail-inject adds a Mail-Followup-To field with all the
To+Cc addresses. qmail-inject does not add Mail-Followup-To
to a message that already has one.
The QMAILINJECT environment variable can contain any of the
following letters:
c Use address-comment style for the From field. Normally
qmail-inject uses name-address style.
s Do not look at any incoming Return-Path field.
Normally, if Return-Path is supplied, it sets the
envelope sender address, overriding all environment
variables. Return-Path is deleted in any case.
f Delete any incoming From field. Normally, if From is
supplied, it overrides the usual From field created by
qmail-inject.
i Delete any incoming Message-ID field. Normally, if
Message-ID is supplied, it overrides the usual
Message-ID field created by qmail-inject.
r Use a per-recipient VERP. qmail-inject will append
each recipient address to the envelope sender of the
copy going to that recipient.
m Use a per-message VERP. qmail-inject will append the
current date and process ID to the envelope sender.
OPTIONS
-a Send the message to all addresses given as recip
arguments; do not use header recipient addresses.
-h Send the message to all header recipient addresses.
For non-forwarded messages, this means the addresses
listed under To, Cc, Bcc, Apparently-To. For forwarded
messages, this means the addresses listed under
Resent-To, Resent-Cc, Resent-Bcc. Do not use any recip
arguments.
-A (Default.) Send the message to all addresses given as
recip arguments. If no recip arguments are supplied,
send the message to all header recipient addresses.
-H Send the message to all header recipient addresses, and
to all addresses given as recip arguments.
-fsender
Pass sender to qmail-queue as the envelope sender
address. This overrides Return-Path and all
environment variables.
-N (Default.) Feed the resulting message to qmail-queue.
-n Print the message rather than feeding it to qmail-
queue.
CONTROL FILES
defaultdomain
Default domain name. Default: me, if that is
supplied; otherwise the literal name defaultdomain,
which is probably not what you want. qmail-inject adds
this name to any host name without dots, including
defaulthost if defaulthost does not have dots.
(Exception: see plusdomain.)
The QMAILDEFAULTDOMAIN environment variable overrides
defaultdomain.
defaulthost
Default host name. Default: me, if that is supplied;
otherwise the literal name defaulthost, which is
probably not what you want. qmail-inject adds this
name to any address without a host name. defaulthost
need not be the current host's name. For example, you
may prefer that outgoing mail show just your domain
name.
The QMAILDEFAULTHOST environment variable overrides
defaulthost.
idhost
Host name for Message-IDs. Default: me, if that is
supplied; otherwise the literal name idhost, which is
certainly not what you want. idhost need not be the
current host's name. For example, you may prefer to
use fake host names in Message-IDs. However, idhost
must be a fully-qualified name within your domain, and
each host in your domain should use a different idhost.
The QMAILIDHOST environment variable overrides idhost.
plusdomain
Plus domain name. Default: me, if that is supplied;
otherwise the literal name plusdomain, which is
probably not what you want. qmail-inject adds this
name to any host name that ends with a plus sign,
including defaulthost if defaulthost ends with a plus
sign. If a host name does not have dots but ends with
a plus sign, qmail-inject uses plusdomain, not
defaultdomain.
The QMAILPLUSDOMAIN environment variable overrides
plusdomain.
