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  op-
	      tions 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) or postlogd(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 (in
	      the case of sendmail(1), with  the  "-C"	option),  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  privileged  Postfix
	      process  will  import  from  a  non-Postfix  parent  process, or
	      name=value environment overrides.

       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)
	      A	prefix that  is	 prepended  to	the  process  name  in	syslog
	      records, so that,	for example, "smtpd" becomes "prefix/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
