       nullmailer-send - Send queued messages


       nullmailer-send [--daemon] [--syslog]


       This  program  is responsible for coordinating the transmission of messages that have been
       queued by nullmailer-queue.  It uses a variety of protocol modules to deliver the messages
       from the queue to remote "smart" servers.

       When  the  program  starts, the queue is scanned to build a list of messages to send.  The
       queue is rescanned when either the trigger is pulled,  or  after  pausetime  seconds  have
       elapsed  after  the  last  failed  delivery.   When  there  are  no messages in the queue,
       nullmailer does no rescanning until the trigger is pulled.  Pulling the  trigger  consists
       of  opening  up  the trigger named pipe and writing a single byte to it, which causes this
       program to be awakened (if it's not already processing the queue).  This procedure is done
       by  nullmailer-queue  to  ensure  that  messages are delivered immediately.  You can start
       delivery by hand from the command line like this:

           echo 1 > trigger

       Delivery of messages consists of reading the list of remote servers  and  then  trying  to
       deliver  the messages to these servers as follows.  For each remote in the list, the named
       protocol handler is executed once for  each  message  remaining  in  the  queue.   If  the
       protocol  handler succeeds, the message is removed from the queue and processing continues
       with the next message.  If it fails, the remote is skipped and processing of  the  remaing
       messages  continues  with  the  next  remote.   When  all  the  remotes  have  been tried,
       nullmailer-send sleeps for a number of seconds  specified  by  pausetime  before  retrying
       sending the contents of the queue.


       -d, --daemon
              Fork into the background, implies --syslog.

       -s, --syslog
              Use  syslog  for  error  and  log  messages.   With  --daemon,  syslog will be used
              exclusively, without --daemon, syslog will be used additionally.


       All the control files are reread each time the queue is run.

              Sets the environment variable $HELOHOST which is used by the SMTP  protocol  module
              to  set  the  parameter given to the HELO command.  Defaults to the value of the me
              configuration file.

              The maximum number of seconds to pause between successive queue runs  (defaults  to

              The minimum number of seconds to pause between successive queue runs when there are
              messages in the queue (defaults to 60).  Each time this  timeout  is  reached,  the
              timeout  is doubled to a maximum of maxpause.  After new messages are injected, the
              timeout is reset.  If this is set to 0, nullmailer-send will exit immediately after
              going through the queue once (one-shot mode).

              This  file  contains  a list of remote servers to which to send each message.  Each
              line of this file contains a remote host name or address followed  by  an  optional
              protocol string, separated by white space.  The protocol name defaults to smtp, and
              may be followed by command-line arguments for that module.  For example, to connect
              to port 2525 on your SMTP smart host, which also requires SMTP authentication, use:

                  smarthost.dom smtp --port=2525 --user=user --pass=pass

              If  your  smarthost  requires  LOGIN  authentication  instead  of the default PLAIN
              method, use:

                  smarthost.dom smtp --port=2525 --auth-login --user=user --pass=pass

              Blank lines and lines starting with a pound  are  ignored.  When  called  with  the
              --help option, each protocol module will list its available command-line arguments:

                  /usr/local/libexec/nullmailer/smtp --help

              The  number of seconds to wait for a remote module listed above to complete sending
              a message before killing it and trying again (defaults to 3600).  If this is set to
              0, nullmailer-send will wait forever for messages to complete sending.
