qmail-inject(8)                                               System Manager's Manual                                              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.

       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,  overrid-
              ing 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  recipi-
              ent.

       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.
