POSTDROP(1)		    General Commands Manual		   POSTDROP(1)



NAME
       postdrop - Postfix mail posting utility

SYNOPSIS
       postdrop [-rv] [-c config_dir]

DESCRIPTION
       The  postdrop(1)	 command  creates a file in the maildrop directory and
       copies its standard input to the file.

       Options:

       -c config_dir
	      The main.cf configuration file is in the named directory instead
	      of the default configuration directory. See also the MAIL_CONFIG
	      environment setting below.

       -r     Use a Postfix-internal protocol for  reading  the	 message  from
	      standard input, and for reporting status information on standard
	      output. This is currently the only supported method.

       -v     Enable verbose  logging  for  debugging  purposes.  Multiple  -v
	      options  make  the  software increasingly verbose. As of Postfix
	      2.3, this option is available for the super-user only.

SECURITY
       The command is designed to run with set-group ID privileges, so that it
       can write to the maildrop queue directory and so that it can connect to
       Postfix daemon processes.

DIAGNOSTICS
       Fatal errors: malformed input, I/O error, out of memory.	 Problems  are
       logged  to syslogd(8) and to the standard error stream.	When the input
       is incomplete, or when the process receives a HUP, INT,	QUIT  or  TERM
       signal, the queue file is deleted.

ENVIRONMENT
       MAIL_CONFIG
	      Directory	 with the main.cf file. In order to avoid exploitation
	      of set-group ID privileges, a non-standard directory is  allowed
	      only if:

	      o	     The  name is listed in the standard main.cf file with the
		     alternate_config_directories configuration parameter.

	      o	     The command is invoked by the super-user.

CONFIGURATION PARAMETERS
       The following main.cf parameters are especially relevant to  this  pro-
       gram.   The  text  below	 provides  only a parameter summary. See post-
       conf(5) for more details including examples.

       alternate_config_directories (empty)
	      A list of non-default Postfix configuration directories that may
	      be  specified with "-c config_directory" on the command line, or
	      via the MAIL_CONFIG environment parameter.

       config_directory (see 'postconf -d' output)
	      The default location of the Postfix main.cf and  master.cf  con-
	      figuration files.

       import_environment (see 'postconf -d' output)
	      The  list	 of environment parameters that a Postfix process will
	      import from a non-Postfix parent process.

       queue_directory (see 'postconf -d' output)
	      The location of the Postfix top-level queue directory.

       syslog_facility (mail)
	      The syslog facility of Postfix logging.

       syslog_name (see 'postconf -d' output)
	      The mail system name that is prepended to the  process  name  in
	      syslog  records,	so  that  "smtpd" becomes, for example, "post-
	      fix/smtpd".

       trigger_timeout (10s)
	      The time limit for sending a trigger to a	 Postfix  daemon  (for
	      example, the pickup(8) or qmgr(8) daemon).

       Available in Postfix version 2.2 and later:

       authorized_submit_users (static:anyone)
	      List  of	users who are authorized to submit mail with the send-
	      mail(1) command (and with the privileged postdrop(1) helper com-
	      mand).

FILES
       /var/spool/postfix/maildrop, maildrop queue
