nullmailer-dsn(1)	    General Commands Manual	     nullmailer-dsn(1)

NAME
       nullmailer-dsn -	Reformat a queued message into a delivery status noti-
       fication	(DSN)

SYNOPSIS
       nullmailer-dsn [	options	] status-code <	message

DESCRIPTION
       This  program  reads  a	nullmailer  queue message from standard	input,
       transforms it into a delivery status notification, and writes  the  re-
       sult  to	 standard output. The output is	formatted to be	fed into null-
       mailer-queue.

       All times in the	options	are expressed as seconds  since	 midnight  GMT
       January 1, 1970 (the UNIX epoch).

OPTIONS
       --diagnostic-code=STRING
	      Sets  the	 actual	 diagnostic code issued	by the mail transport.
	      Must be in the form of "type; text", where type would  typically
	      be the protocol name, such as SMTP.  This	adds a Diagnostic-Code
	      header for each recipient.

       --envelope-id=STRING
	      Original	envelope  ID. Setting this adds	a Original-Envelope-Id
	      header to	the delivery status section.

       --last-attempt=TIME
	      Sets the time of the last	attempted delivery.  Defaults  to  the
	      access  time  of	the  input message.  This sets the date	in the
	      Last-Attempt-Date	header for each	recipient.

       --max-lines=COUNT
	      Sets the maximum number of lines of the original message to copy
	      into the generated message.  A value of  zero  copies  only  the
	      original	header.	  Negative values copy the whole message.  De-
	      faults to	bouncelines below, or zero if that is empty.

       --orig-timestamp=TIME
	      Sets the time of the original message. Defaults  to  the	change
	      time  of	the  input message. This sets the date in the Arrival-
	      Date header in the delivery status section.

       --remote=STRING
	      Sets the name of the remote MTA server.  This adds a  Remote-MTA
	      header for each recipient.

       --retry-until=TIME
	      Sets  the	 time  of  the (future)	final delivery attempt.	No de-
	      fault. This adds a Will-Retry-Until header for each recipient.

RETURN VALUE
       Exits 0 if it was successful, otherwise it prints a diagnostic  message
       to standard error and exits 1.

CONTROL	FILES
       adminaddr
	      If doublebounceto	is empty, double bounces are delivered to this
	      address  instead.	  If  no address is configured,	double bounces
	      are not generated.

       bouncelines
	      Sets the maximum number of lines	of  the	 original  message  to
	      copy.  May be overridden by --max-lines as above.

       bounceto
	      The  address  to	which  all  bounces  should be sent.  If it is
	      empty, the original sender address is used.

       defaultdomain
	      The content of this file is appended to any host name that  does
	      not  contain  a period (except localhost), including defaulthost
	      and idhost.  Defaults to the value of the	me control file, if it
	      exists, otherwise	the literal name defaultdomain.

       defaulthost
	      The content of this file is appended  to	any  address  that  is
	      missing  a  host	name.  Defaults	to the value of	the me control
	      file, if it exists, otherwise the	literal	name defaulthost.

       doublebounceto
	      If the original sender was empty (the original message was a de-
	      livery status or disposition notification), the double bounce is
	      sent to the address in this file.

       idhost The content of this file is used when  building  the  message-id
	      string  for the message.	Defaults to the	canonicalized value of
	      defaulthost.

       me     The fully-qualified host name  of	 the  computer	running	 null-
	      mailer.  Defaults	to the literal name me.
