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 reci-
pients.
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 environ-
ment 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.
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. Nor-
mally, 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 argu-
ments; 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 environ-
ment 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 sup-
plied; 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. (Excep-
tion: see plusdomain.)
The QMAILDEFAULTDOMAIN environment variable overrides
defaultdomain.
defaulthost

qmail-inject(8) Maintenance Procedures qmail-inject(8)
Default host name. Default: me, if that is supplied;
otherwise the literal name defaulthost, which is prob-
ably 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 prob-
ably 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.
