NAME

       qmail-send - deliver mail messages from the queue

SYNOPSIS

       qmail-send

DESCRIPTION

       qmail-send  handles  messages  placed  into  the  outgoing queue by qmail-queue.  It uses qmail-lspawn to
       deliver messages to local recipients and qmail-rspawn to deliver messages to  remote  recipients.   If  a
       message  is  temporarily  undeliverable  to  one or more addresses, qmail-send leaves it in the queue and
       tries the addresses again later.

       qmail-send prints a readable record of its activities to descriptor 0.   It  writes  commands  to  qmail-
       lspawn, qmail-rspawn, and qmail-clean on descriptors 1, 3, and 5, and reads responses from descriptors 2,
       4, and 6.  qmail-send is responsible for avoiding deadlock.

       If qmail-send receives a TERM signal, it will exit cleanly, after waiting (possibly more than  a  minute)
       for current delivery attempts to finish.

       If  qmail-send  receives  an  ALRM  signal,  it  will reschedule every message in the queue for immediate
       delivery.

CONTROL FILES

       WARNING: qmail-send reads its control files only when it starts.  If you change the  control  files,  you
       must  stop and restart qmail-send.  Exception: If qmail-send receives a HUP signal, it will reread locals
       and virtualdomains.

       bouncefrom
            Bounce username.  Default: MAILER-DAEMON.

       bouncehost
            Bounce host.  Default: me, if that is supplied; otherwise the  literal  name  bouncehost,  which  is
            probably  not  what you want.  If a message is permanently undeliverable, qmail-send sends a single-
            bounce notice back to the message's envelope sender.  The  notice  is  From:  bouncefrom@bouncehost,
            although its envelope sender is empty.

       concurrencylocal
            Maximum  number  of simultaneous local delivery attempts.  Default: 10.  If 0, local deliveries will
            be put on hold.  concurrencylocal is limited at compile time to 120.

       concurrencyremote
            Maximum number of simultaneous remote delivery attempts.  Default: 20.  If 0, remote deliveries will
            be put on hold.  concurrencyremote is limited at compile time to 120.

       doublebouncehost
            Double-bounce  host.  Default: me, if that is supplied; otherwise the literal name doublebouncehost,
            which is probably not what you want.

       doublebounceto
            User to receive double-bounces.  Default: postmaster.  If  a  single-bounce  notice  is  permanently
            undeliverable, qmail-send sends a double-bounce notice to doublebounceto@doublebouncehost.  (If that
            bounces, qmail-send gives up.)

       envnoathost
            Presumed domain name for addresses without @ signs.  Default: me, if that is supplied; otherwise the
            literal  name  envnoathost,  which  is  probably  not what you want.  If qmail-send sees an envelope
            recipient address without an @ sign, it appends @envnoathost.

       locals
            List of domain names that the current host receives mail for, one per line.  Default: me, if that is
            supplied; otherwise qmail-send refuses to run.  An address user@domain is considered local if domain
            is listed in locals.

       percenthack
            List of domain names where the percent hack is applied.  If domain is  listed  in  percenthack,  any
            address  of the form user%fqdn@domain is rewritten as user@fqdn.  user may contain %, so the percent
            hack may be applied repeatedly.  qmail-send handles percenthack before locals.

       queuelifetime
            Number of seconds a message can stay in the queue.  Default: 604800 (one  week).   After  this  time
            expires,  qmail-send  will  try  the  message  once  more,  but it will treat any temporary delivery
            failures as permanent failures.

       virtualdomains
            List of virtual users or domains, one per line.  A virtual user has  the  form  user@domain:prepend,
            without any extra spaces.  When qmail-send sees the recipient address user@domain, it converts it to
            prepend-user@domain and treats it as local.

            A virtual domain has the form domain:prepend.  It applies to any recipient address at  domain.   For
            example, if

                 nowhere.mil:joe-foo

            is  in  virtualdomains,  and  a  message  arrives  for info@nowhere.mil, qmail-send will rewrite the
            recipient address as joe-foo-info@nowhere.mil and deliver the message locally.

            virtualdomains may contain wildcards:

                 .fax:uucp-fax
                 :alias-catchall
                 .nowhere.mil:joe-foo-host

            virtualdomains may also contain exceptions: an empty prepend means that  domain  is  not  a  virtual
            domain.

            qmail-send handles virtualdomains after locals: if a domain is listed in locals, virtualdomains does
            not apply.
