NAME

       nullmailer-dsn - Reformat a queued message into a delivery status notification (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 result  to  standard  output.  The  output  is  formatted  to  be  fed  into
       nullmailer-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.   Defaults
              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 default. 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 delivery 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 nullmailer.  Defaults to  the  literal  name
              me.
