Postfix queue control
\fBpostqueue\fR [\fB-v\fR] [\fB-c \fIconfig_dir\fR] \fB-f\fR
\fBpostqueue\fR [\fB-v\fR] [\fB-c \fIconfig_dir\fR] \fB-i \fIqueue_id\fR
\fBpostqueue\fR [\fB-v\fR] [\fB-c \fIconfig_dir\fR] \fB-p\fR
\fBpostqueue\fR [\fB-v\fR] [\fB-c \fIconfig_dir\fR] \fB-s \fIsite\fR
The \fBpostqueue\fR(1) command implements the Postfix user interface
for queue management. It implements operations that are
traditionally available via the \fBsendmail\fR(1) command.
See the \fBpostsuper\fR(1) command for queue operations
that require super-user privileges such as deleting a message
from the queue or changing the status of a message.

The following options are recognized:
.IP "\fB-c \fIconfig_dir\fR"
The \\fR configuration file is in the named directory
instead of the default configuration directory. See also the
MAIL_CONFIG environment setting below.
.IP \fB-f\fR
Flush the queue: attempt to deliver all queued mail.

This option implements the traditional "\fBsendmail -q\fR" command,
by contacting the Postfix \fBqmgr\fR(8) daemon.

Warning: flushing undeliverable mail frequently will result in
poor delivery performance of all other mail.
.IP "\fB-i \fIqueue_id\fR"
Schedule immediate delivery of deferred mail with the
specified queue ID.

This option implements the traditional \fBsendmail -qI\fR
command, by contacting the \fBflush\fR(8) server.

This feature is available with Postfix version 2.4 and later.
.IP \fB-p\fR
Produce a traditional sendmail-style queue listing.
This option implements the traditional \fBmailq\fR command,
by contacting the Postfix \fBshowq\fR(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 implemented
by executing the \fBpostqueue\fR(1) command. The queue ID string
is followed by an optional status character:
.IP \fB*\fR
The message is in the \fBactive\fR queue, i.e. the message is
selected for delivery.
.IP \fB!\fR
The message is in the \fBhold\fR queue, i.e. no further delivery
attempt will be made until the mail is taken off hold.
.IP "\fB-s \fIsite\fR"
Schedule immediate delivery of all mail that is queued for the named
\fIsite\fR. A numerical site must be specified as a valid RFC 2821
address literal enclosed in [], just like in email addresses.
The site must be eligible for the "fast flush" service.
See \fBflush\fR(8) for more information about the "fast flush"

This option implements the traditional "\fBsendmail -qR\fIsite\fR"
command, by contacting the Postfix \fBflush\fR(8) daemon.
.IP \fB-v\fR
Enable verbose logging for debugging purposes. Multiple \fB-v\fR
options make the software increasingly verbose. As of Postfix 2.3,
this option is available for the super-user only.
This program is designed to run with set-group ID privileges, so
that it can connect to Postfix daemon processes.
Problems are logged to \fBsyslogd\fR(8) and to the standard error
Directory with the \\fR file. In order to avoid exploitation
of set-group ID privileges, a non-standard directory is allowed only
.IP \(bu
The name is listed in the standard \\fR file with the
\fBalternate_config_directories\fR configuration parameter.
.IP \(bu
The command is invoked by the super-user.
The following \\fR parameters are especially relevant to
this program.
The text below provides only a parameter summary. See
\fBpostconf\fR(5) for more details including examples.
.IP "\fBalternate_config_directories (empty)\fR"
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.
.IP "\fBconfig_directory (see 'postconf -d' output)\fR"
The default location of the Postfix and
configuration files.
.IP "\fBcommand_directory (see 'postconf -d' output)\fR"
The location of all postfix administrative commands.
.IP "\fBfast_flush_domains ($relay_domains)\fR"
Optional list of destinations that are eligible for per-destination
logfiles with mail that is queued to those destinations.
.IP "\fBimport_environment (see 'postconf -d' output)\fR"
The list of environment parameters that a Postfix process will
import from a non-Postfix parent process.
.IP "\fBqueue_directory (see 'postconf -d' output)\fR"
The location of the Postfix top-level queue directory.
.IP "\fBsyslog_facility (mail)\fR"
The syslog facility of Postfix logging.
.IP "\fBsyslog_name (postfix)\fR"
The mail system name that is prepended to the process name in syslog
records, so that "smtpd" becomes, for example, "postfix/smtpd".
.IP "\fBtrigger_timeout (10s)\fR"
The time limit for sending a trigger to a Postfix daemon (for
example, the \fBpickup\fR(8) or \fBqmgr\fR(8) daemon).
Available in Postfix version 2.2 and later:
.IP "\fBauthorized_flush_users (static:anyone)\fR"
List of users who are authorized to flush the queue.
.IP "\fBauthorized_mailq_users (static:anyone)\fR"
List of users who are authorized to view the queue.
