qmail inject.8

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.

qmail-inject rewrites the sender using Sender Rewriting Scheme if SRS** has been configured. see** qmail-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.

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.

If QMAILQUEUE environment variable is set to /usr/sbin/qmail-multi, qmail-inject gets the ability to multiplex queues. 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 $HOME/.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, $HOME/.defaultqueue is not processed.

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.

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 overriden 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
