qmail-send - deliver mail messages from the queue


          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.

          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.

               Bounce username.  Default:  MAILER-DAEMON.

               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.

               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

               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.

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

               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.)

               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.

               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.

               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

               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

               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


               is in virtualdomains, and a message arrives for
     , qmail-send will rewrite the recipient
               address as and deliver the
               message locally.

               virtualdomains may contain wildcards:


               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
