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  out-
	      put. 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  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, 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 program.  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 configuration 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, "postfix/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 sendmail(1) command (and with the privileged postdrop(1) helper command).

FILES

       /var/spool/postfix/maildrop, maildrop queue
