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.
