POSTQUEUE(1) 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 inter-
face for queue management. It implements all the opera-
tions 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 com-
mand, by contacting the Postfix showq(8) daemon.
Each queue entry shows the queue file ID, message
size, arrival time, sender, and the recipients that
still need to be delivered. If mail could not be
delivered upon the last attempt, the reason for
failure is shown. This mode of operation is imple-
mented by executing the postqueue(1) command. The
queue ID string is followed by an optional status
character:
* The message is in the active queue, i.e. the
message is selected for delivery.
! The message is in the hold queue, i.e. no
further delivery attempt will be made until
the mail is taken off hold.
-s site
Schedule immediate delivery of all mail that is
queued for the named site. The site must be eligi-
ble 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. Mul-
tiple -v options make the software increasingly
verbose.
SECURITY
This program is designed to run with set-group ID privi-
leges, 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 parame-
ter value.
Only the superuser 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" ser-
vice (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.
