       sendmail - Postfix to Sendmail compatibility interface

       sendmail [option ...] [recipient ...]

       sendmail -bp

       sendmail -I

       The Postfix sendmail(1) command implements the Postfix to Sendmail com
       patibility interface.  For the  sake  of  compatibility	with  existing
       applications,  some  Sendmail  command-line  options are recognized but
       silently ignored.

       By default, Postfix sendmail(1) reads a	message  from  standard  input
       until  EOF  or  until  it  reads  a  line  with only a . character, and
       arranges for delivery.  Postfix sendmail(1) relies on  the  postdrop(1)
       command to create a queue file in the maildrop directory.

       Specific  command aliases are provided for other common modes of opera

       mailq  List the mail queue. Each entry shows the queue file ID, message
	      size,  arrival  time, sender, and the recipients that still need
	      to be delivered.	If mail could not be delivered upon  the  last
	      attempt, the reason for failure is shown. This mode of operation
	      is implemented by executing the postqueue(1) command.

	      Initialize the alias database.  If no input  file  is  specified
	      (with  the  -oA  option,	see  below), the program processes the
	      file(s) specified with the alias_database configuration  parame
	      ter.   If  no alias database type is specified, the program uses
	      the type specified with the default_database_type  configuration
	      parameter.  This mode of operation is implemented by running the
	      postalias(1) command.

	      Note: it may take a minute or so before an alias database update
	      becomes  visible.  Use the "postfix reload" command to eliminate
	      this delay.

       These and other features can be selected by specifying the  appropriate
       combination  of	command-line  options. Some features are controlled by
       parameters in the main.cf configuration file.

       The following options are recognized:

       -Am (ignored)

       -Ac (ignored)
	      Postfix sendmail uses the same configuration file regardless  of
	      whether or not a message is an initial submission.

       -B body_type
	      The message body MIME type: 7BIT or 8BITMIME.

       -bd    Go  into	daemon	mode. This mode of operation is implemented by
	      executing the "postfix start" command.

       -bh (ignored)

       -bH (ignored)
	      Postfix has no persistent host status database.

       -bi    Initialize alias database. See the newaliases command above.

       -bm    Read mail from standard input and arrange for delivery.  This is
	      the default mode of operation.

       -bp    List the mail queue. See the mailq command above.

       -bs    Stand-alone  SMTP  server mode. Read SMTP commands from standard
	      input, and write responses to standard output.   In  stand-alone
	      SMTP  server  mode,  mail relaying and other access controls are
	      disabled by default. To enable them,  run  the  process  as  the
	      mail_owner user.

	      This  mode  of  operation is implemented by running the smtpd(8)

       -bv    Do not collect or deliver a  message.  Instead,  send  an  email
	      report  after  verifying each recipient address.	This is useful
	      for testing address rewriting and routing configurations.

	      This feature is available in Postfix version 2.1 and later.

       -C config_file

       -C config_dir
	      The path name of the Postfix main.cf  file,  or  of  its	parent
	      directory.  This	information  is  ignored with Postfix versions
	      before 2.3.

	      With all Postfix versions, you can specify a directory  pathname
	      with  the MAIL_CONFIG environment variable to override the loca
	      tion of configuration files.

       -F full_name
	      Set the sender full name. This overrides	the  NAME  environment
	      variable, and is used only with messages that have no From: mes
	      sage header.

       -f sender
	      Set the envelope sender  address.  This  is  the	address  where
	      delivery problems are sent to. With Postfix versions before 2.1,
	      the  Errors-To:  message	header	overrides  the	error	return

       -G     Gateway  (relay)	submission, as opposed to initial user submis
	      sion.  Either do not rewrite addresses at all, or update	incom
	      plete  addresses	with  the  domain  information	specified with

	      This option is ignored before Postfix version 2.3.

       -h hop_count (ignored)
	      Hop count limit. Use the hopcount_limit configuration  parameter

       -I     Initialize alias database. See the newaliases command above.

       -i     When  reading  a message from standard input, dont treat a line
	      with only a . character as the end of input.

       -L label (ignored)
	      The logging label. Use the syslog_name  configuration  parameter

       -m (ignored)
	      Backwards compatibility.

       -N dsn (default: delay, failure)
	      Delivery	status	notification  control. Specify either a comma-
	      separated list with one or more of  failure  (send  notification
	      when  delivery fails), delay (send notification when delivery is
	      delayed), or success (send  notification	when  the  message  is
	      delivered);  or  specify	never (dont send any notifications at

	      This feature is available in Postfix 2.3 and later.

       -n (ignored)
	      Backwards compatibility.

	      Non-default alias database. Specify pathname  or	type:pathname.
	      See postalias(1) for details.

       -O option=value (ignored)
	      Backwards compatibility.

       -o7 (ignored)

       -o8 (ignored)
	      To  send 8-bit or binary content, use an appropriate MIME encap
	      sulation and specify the appropriate -B command-line option.

       -oi    When reading a message from standard input, dont treat  a  line
	      with only a . character as the end of input.

       -om (ignored)
	      The sender is never eliminated from alias etc. expansions.

       -o x value (ignored)
	      Set  option x to value. Use the equivalent configuration parame
	      ter in main.cf instead.

       -r sender
	      Set the envelope sender  address.  This  is  the	address  where
	      delivery problems are sent to. With Postfix versions before 2.1,
	      the  Errors-To:  message	header	overrides  the	error	return

       -R return_limit (ignored)
	      Limit  the  size of bounced mail. Use the bounce_size_limit con
	      figuration parameter instead.

       -q     Attempt to deliver all queued mail. This is implemented by  exe
	      cuting the postqueue(1) command.

	      Warning:	flushing  undeliverable mail frequently will result in
	      poor delivery performance of all other mail.

       -qinterval (ignored)
	      The interval between queue runs. Use the queue_run_delay config
	      uration parameter instead.

	      Schedule	immediate  delivery of all mail that is queued for the
	      named site.  This  option  accepts  only	site  names  that  are
	      eligible	for  the  "fast  flush" service, and is implemented by
	      executing the  postqueue(1)  command.   See  flush(8)  for  more
	      information about the "fast flush" service.

	      This  command  is  not implemented. Use the slower "sendmail -q"
	      command instead.

       -t     Extract recipients from message headers. These are added to  any
	      recipients specified on the command line.

	      With Postfix versions prior to 2.1, this option requires that no
	      recipient addresses are specified on the command line.

       -U (ignored)
	      Initial user submission.

       -V envid
	      Specify the envelope ID for notification by servers that support

	      This feature is available in Postfix 2.3 and later.

       -XV (Postfix 2.2 and earlier: -V)
	      Variable	Envelope Return Path. Given an envelope sender address
	      of the form owner-listname@origin,  each	recipient  user@domain
	      receives mail with a personalized envelope sender address.

	      By  default,  the personalized envelope sender address is owner-
	      listname+user=domain@origin. The default + and = characters  are
	      configurable   with  the	default_verp_delimiters  configuration

       -XVxy (Postfix 2.2 and earlier: -Vxy)
	      As -XV, but uses x and  y  as  the  VERP	delimiter  characters,
	      instead of the characters specified with the default_verp_delim
	      iters configuration parameter.

       -v     Send an email report of the first delivery attempt (Postfix ver
	      sions  2.1 and later). Mail delivery always happens in the back
	      ground. When multiple -v options are given, enable verbose  log
	      ging for debugging purposes.

       -X log_file (ignored)
	      Log mailer traffic. Use the debug_peer_list and debug_peer_level
	      configuration parameters instead.

       By design, this program is not set-user (or group) id. However, it must
       handle  data  from  untrusted  users  or untrusted machines.  Thus, the
       usual precautions need to be taken against malicious inputs.

       Problems are logged to syslogd(8) and to the standard error stream.
