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.
