POSTQUEUE(1)						      General Commands Manual						      POSTQUEUE(1)

NAME
       postqueue - Postfix queue control

SYNOPSIS
       postqueue [-c config_dir] -f
       postqueue [-c config_dir] -p
       postqueue [-c config_dir] -s site

DESCRIPTION
       The  postqueue  program implements the Postfix user interface for queue management. It implements all the operations that are traditionally
       available via the sendmail(1) command.

       The following options are recognized:

       -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.

       -f     Flush the queue: attempt to deliver all queued mail.

	      This option implements the traditional sendmail -q command, by contacting the Postfix qmgr(8) daemon.

       -p     Produce a traditional sendmail-style queue listing.

	      This option implements the traditional mailq command, by contacting the Postfix showq(8) daemon.

       -s site
	      Schedule	immediate  delivery of all mail that is queued for the named site. The site must be eligible for the "fast flush" service.
	      See flush(8) for more information about the "fast flush" service.

	      This option implements the traditional sendmail -qRsite command, by contacting the Postfix flush(8) daemon.

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

SECURITY
       This program is designed to run with set-group ID privileges, so that it can connect to Postfix daemon processes.

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

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
       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.

       fast_flush_domains
	      List  of	domains  that  will receive "fast flush" service (default: all domains that this system is willing to relay mail to). This
	      list specifies the domains that Postfix accepts in the SMTP ETRN request and in the sendmail -qR command.
