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.
