qmail-inject - preprocess and send a mail message
qmail-inject [ -nNaAhH ] [ -fsender ] [ recip ... ]
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.
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.
-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.
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.
