POSTQUEUE(1) POSTQUEUE(1)
<b>NAME</b>
postqueue - Postfix queue control
<b>SYNOPSIS</b>
<b>postqueue</b> [<b>-v</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>] <b>-f</b>
<b>postqueue</b> [<b>-v</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>] <b>-i</b> <i>queue</i><b>_</b><i>id</i>
<b>postqueue</b> [<b>-v</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>] <b>-p</b>
<b>postqueue</b> [<b>-v</b>] [<b>-c</b> <i>config</i><b>_</b><i>dir</i>] <b>-s</b> <i>site</i>
<b>DESCRIPTION</b>
The <a href="postqueue.1.html"><b>postqueue</b>(1)</a> command implements the Postfix user
interface for queue management. It implements operations
that are traditionally available via the <a href="sendmail.1.html"><b>sendmail</b>(1)</a> com-
mand. See the <a href="postsuper.1.html"><b>postsuper</b>(1)</a> command for queue operations
that require super-user privileges such as deleting a mes-
sage from the queue or changing the status of a message.
The following options are recognized:
<b>-c</b> <i>config</i><b>_</b><i>dir</i>
The <a href="postconf.5.html"><b>main.cf</b></a> configuration file is in the named
directory instead of the default configuration
directory. See also the MAIL_CONFIG environment
setting below.
<b>-f</b> Flush the queue: attempt to deliver all queued
mail.
This option implements the traditional "<b>sendmail</b>
<b>-q</b>" command, by contacting the Postfix <a href="qmgr.8.html"><b>qmgr</b>(8)</a> dae-
mon.
Warning: flushing undeliverable mail frequently
will result in poor delivery performance of all
other mail.
<b>-i</b> <i>queue</i><b>_</b><i>id</i>
Schedule immediate delivery of deferred mail with
the specified queue ID.
This option implements the traditional <b>sendmail -qI</b>
command, by contacting the <a href="flush.8.html"><b>flush</b>(8)</a> server.
This feature is available with Postfix version 2.4
and later.
<b>-p</b> Produce a traditional sendmail-style queue listing.
This option implements the traditional <b>mailq</b> com-
mand, by contacting the Postfix <a href="showq.8.html"><b>showq</b>(8)</a> 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. The queue ID string is followed
by an optional status character:
<b>*</b> The message is in the <b>active</b> queue, i.e. the
message is selected for delivery.
<b>!</b> The message is in the <b>hold</b> queue, i.e. no
further delivery attempt will be made until
the mail is taken off hold.
<b>-s</b> <i>site</i>
Schedule immediate delivery of all mail that is
queued for the named <i>site</i>. A numerical site must be
specified as a valid <a href="http://tools.ietf.org/html/rfc2821">RFC 2821</a> address literal
enclosed in [], just like in email addresses. The
site must be eligible for the "fast flush" service.
See <a href="flush.8.html"><b>flush</b>(8)</a> for more information about the "fast
flush" service.
This option implements the traditional "<b>sendmail</b>
<b>-qR</b><i>site</i>" command, by contacting the Postfix
<a href="flush.8.html"><b>flush</b>(8)</a> daemon.
<b>-v</b> Enable verbose logging for debugging purposes. Mul-
tiple <b>-v</b> options make the software increasingly
verbose. As of Postfix 2.3, this option is avail-
able for the super-user only.
<b>SECURITY</b>
This program is designed to run with set-group ID privi-
leges, so that it can connect to Postfix daemon processes.
<b>DIAGNOSTICS</b>
Problems are logged to <b>syslogd</b>(8) and to the standard
error stream.
<b>ENVIRONMENT</b>
MAIL_CONFIG
Directory with the <a href="postconf.5.html"><b>main.cf</b></a> file. In order to avoid
exploitation of set-group ID privileges, a non-
standard directory is allowed only if:
<b>o</b> The name is listed in the standard <a href="postconf.5.html"><b>main.cf</b></a>
file with the <b><a href="postconf.5.html#alternate_config_directories">alternate_config_directories</a></b>
configuration parameter.
<b>o</b> The command is invoked by the super-user.
<b>CONFIGURATION PARAMETERS</b>
