qmail-inject - preprocess and send a mail message
qmail-inject [ -nNaAhH ] [ -fsender ] [ recip ... ]
qmail-inject reads a mail message from its standard input, adds appropriate information to the message header, and by default invokes qmail-queue(8) to send the message to one or more recipients. You can set QMAILQUEUE environment variable to call any other program that has the same interface as qmail-queue. QMAILQUEUE can be list of multiple programs separated by a white space. e.g. you can set QMAILQUEUE to insert DKIM header as well as filter spam as below.
QMAILQUEUE="/usr/sbin/qmail-dkim /usr/sbin/qmail-spamfilter"
qmail-inject rewrites the sender using Sender Rewriting Scheme if SRS** has been configured. See indimail-srs**(5) for information on how to do this.
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.
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.
If QMAILQUEUE environment variable is set to /usr/sbin/qmail-multi, qmail-inject gets the ability to multiplex queues and filter emails. See qmail-multi(8).
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.
n
Print the message rather than feeding it to
qmail-inject uses environment set according to files in $/var/indimail/.defaultqueue directory. If QUEUE_BASE environment variable is not set, it additionally uses environment set according to files in /etc/indimail/control/defaultqueue directory. If the environment variable FASTQUEUE is set, $/var/indimail/.defaultqueue is not processed.
-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.
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.
maxrecipients
maxrecipients is the number of RCPT TO:'s qmail-inject will accept.
Default: 0 which means no restriction. The environment variable
MAXRECIPIENTS overrides the value in this control file.
domainqueue
Specific queue can be assigned to recipient domains. The format of this
file is of the form
domain:QUEUEDIR=queue_dir
where domain is the recipient domain and queue_dir is any queue which is part of indimail's queue collection. You could also specify a set of queues for a domain.
domain:QUEUE_COUNT=5,QUEUE_START=6,QUEUE_BASE=/var/indimail/queue
specifies that any emails to *@domain be queued in /var/indimail/queue/queue[6,7,8,9,10]. You can use domainqueue to queue mails for certain domains into specific domains and specify individual concurrencies for these queues (see qmail-send(8)). e.g. having
yahoo.com:QUEUEDIR=/var/indimail/queue/queue6
in /etc/indimail/control/domainqueue and
10
in /etc/indimail/control/concurrencyr.queue6
will set 10 as the remote concurrency for all emails sent to yahoo.com
envrules
Specific environment variables can be set for specific senders. The
format of this file is of the form
pat:envar1=val,envar2=val,...]
where pat is a regular expression which matches a sender. envar1, envar2 are list of environment variables to be set.
The name of the control file can be overridden by the environment variable FROMRULES. The following environment variables used by qmail-queue can be set by using envrules.
SCANCMD, QHPSI, QHPSIMINSIZE, QHPSIMAXSIZE, QHPSIRC, EXTRAQUEUE, USE_FSYNC, QQEH, BADEXT, BADEXTPATTERNS, QREGEX, QMAILNAME, MAILNAME, NAME, REMOVEHEADERS, ENVHEADERS, LOGHEADERS, LOGHEADERFD, LOGFILTER, TMPDIR, VIRUSCHECK, VIRUSFORWARD, QUARANTINE, RELAYCLIENT, MAKESEEKABLE, FILTERARGS, QMAILQUEUE, QUEUEPROG, QUEUEDIR, QUEUE_BASE, QUEUE_START, QUEUE_COUNT, QUEUE_PLUGIN, PLUGINDIR, MIN_FREE, ERROR_FD, DKSIGN, DKVERIFY, DKSIGNOPTIONS, DKQUEUE, DKEXCLUDEHEADERS, DKIMSIGN, DKIMVERIFY, DKIMPRACTICE, DKIMIDENTITY, DKIMEXPIRE, SIGN_PRACTICE DKIMQUEUE, SIGNATUREDOMAINS, and NOSIGNATUREDOMAINS
