.SH SYNOPSIS

.B qmail-inject

[

.B \-nNaAhH

] [

.B \-f\fIsender

] [

.I recip ...

]

.SH DESCRIPTION

.B qmail-inject

reads a mail message from its standard input,

adds appropriate information to the message header,

and invokes

.B qmail-queue

to send the message

to one or more recipients.

See

.B qmail-header(5)

for information on how

.B qmail-inject

rewrites header fields.

.B 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.

.SH "ENVIRONMENT VARIABLES"

For the convenience of users who do not run

.B qmail-inject

directly,

.B qmail-inject

takes many options through environment variables.

The user name in the

.B From

header field is set by

.BR QMAILUSER ,

.BR MAILUSER ,

.BR USER ,

or

.BR LOGNAME ,

whichever comes first.

The host name is normally set by the

.I defaulthost

control

but can be overridden with

.B QMAILHOST

or

.BR MAILHOST .

The personal name is

.BR QMAILNAME ,

.BR MAILNAME ,

or

.BR NAME .

The default envelope sender address is the same as the

default

.B From

address,

but it can be overridden with

.B QMAILSUSER

and

.BR QMAILSHOST .

It may also be modified by the

.B r

and

.B m

letters described below.

Bounces will be sent to this address.

If

.B QMAILMFTFILE

is set,

.B 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),

.B qmail-inject

adds a Mail-Followup-To field

with all the To+Cc addresses.

.B qmail-inject

does not add Mail-Followup-To

to a message that already has one.

The

.B QMAILINJECT

environment variable

can contain any of the following letters:

.TP

.B c

Use address-comment style for the

.B From

field.

Normally

.B qmail-inject

uses name-address style.

.TP

.B s

Do not look at any incoming

.B Return-Path

field.

Normally, if

.B Return-Path

is supplied, it sets the envelope sender address,

overriding all environment variables.

.B Return-Path

is deleted in any case.

.TP

.B f

Delete any incoming

.B From

field.

Normally, if

.B From

is supplied, it overrides the usual

.B From

field created by

.BR qmail-inject .

.TP

.B i

Delete any incoming

.B Message-ID

field.

Normally, if

.B Message-ID

is supplied, it overrides the usual

.B Message-ID

field created by

.BR qmail-inject .

.TP

.B r

Use a per-recipient VERP.

.B qmail-inject

will append each recipient address to the envelope sender

of the copy going to that recipient.

.TP

.B m

Use a per-message VERP.

.B qmail-inject

will append the current date and process ID to the envelope sender.

Send the message to all addresses given as

.I recip

.BR Bcc ,

.BR Apparently-To .

Send the message to all header recipient addresses,

and to all addresses given as

to

.SH "CONTROL FILES"

.TP 5

.I defaultdomain

Default domain name.

Default:

.IR me ,

if that is supplied;

otherwise the literal name

.BR defaultdomain ,

which is probably not what you want.

.B qmail-inject

adds this name to any host name without dots,

including

.I defaulthost

if

.I defaulthost

does not have dots.

(Exception: see

.IR plusdomain .)

The

.B QMAILDEFAULTDOMAIN

environment variable

overrides

.IR defaultdomain .

.TP 5

.I defaulthost

Default host name.

Default:

.IR me ,

if that is supplied;

otherwise the literal name

.BR defaulthost ,

which is probably not what you want.

.B qmail-inject

adds this name to any address without a host name.

.I defaulthost

need not be the current host's name.

For example,

you may prefer that outgoing mail show

just your domain name.

The

.B QMAILDEFAULTHOST

environment variable overrides

.IR defaulthost .

.TP 5

.I idhost

Host name for Message-IDs.

Default:

.IR me ,

if that is supplied;

otherwise the literal name

.BR idhost ,

which is certainly not what you want.

.I idhost

need not be the current host's name.

For example, you may prefer to use fake

host names in Message-IDs.

However,

.I idhost

must be a fully-qualified name within your domain,

and each host in your domain should use a different

.IR idhost .

The

.B QMAILIDHOST

environment variable overrides

.IR idhost .

.TP 5

.I plusdomain

Plus domain name.

Default:

.IR me ,

if that is supplied;

otherwise the literal name

.BR plusdomain ,

which is probably not what you want.

.B qmail-inject

adds this name to any host name that ends with a plus sign,

including

.I defaulthost

if

.I defaulthost

ends with a plus sign.

If a host name does not have dots but ends with a plus sign,

.B qmail-inject

uses

.IR plusdomain ,

not

.IR defaultdomain .

The

.B QMAILPLUSDOMAIN

environment variable overrides

.IR plusdomain .
