NAME

       nullmailer-send - Send queued messages

SYNOPSIS

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

DESCRIPTION

       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.

       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 num-
       ber of seconds specified by pausetime before retrying sending the contents of the queue.

OPTIONS

       -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  addi-
	      tionally.

CONTROL FILES

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

       helohost
	      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.

       pausetime
	      The number of seconds to pause between successive queue runs when there are messages in the queue (defaults to 60).  If this is  set
	      to 0, nullmailer-send will exit immediately after going through the queue once (one-shot mode).

       remotes
	      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.

       sendtimeout
	      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.

FILES

       /var/spool/nullmailer/queue
	      The message queue.

       /var/spool/nullmailer/trigger
	      A trigger file to cause immediate delivery.

       /etc/nullmailer
	      The configuration directory.

       /usr/lib/nullmailer
	      The protocol program directory.
