POSTDROP(1)						      General Commands Manual						       POSTDROP(1)

NAME

       postdrop - Postfix mail posting utility

SYNOPSIS

       postdrop [-rv] [-c config_dir]

DESCRIPTION

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

       Options:

       -c     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  out-
	      put. This is currently the only supported method.

       -v     Enable verbose logging for debugging purposes. Multiple -v options make the software increasingly verbose.

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 con-
       nect 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, it is not possible to specify arbitrary
	      directory names.

	      A non-standard directory is allowed only if the name is listed in the standard main.cf  file,  in  the  alternate_config_directories
	      configuration parameter value.

	      Only the super-user is allowed to specify arbitrary directory names.

FILES

       /var/spool/postfix, mail queue
       /etc/postfix, configuration files

CONFIGURATION PARAMETERS

       See the Postfix main.cf file for syntax details and for default values. Use the postfix reload command after a configuration change.

       import_environment
	      List of names of environment parameters that can be imported from non-Postfix processes.

       queue_directory
	      Top-level directory of the Postfix queue. This is also the root directory of Postfix daemons that run chrooted.
