+POSTSUPER(1) POSTSUPER(1)
+
+<b>NAME</b>
+ postsuper - Postfix superintendent
+
+<b>SYNOPSIS</b>
+ <b>postsuper</b> [<b>-psSv</b>]
+ [<b>-c</b> <i>config</i><b>_</b><i>dir</i>] [<b>-d</b> <i>queue</i><b>_</b><i>id</i>]
+ [<b>-e</b> <i>queue</i><b>_</b><i>id</i>] [<b>-f</b> <i>queue</i><b>_</b><i>id</i>]
+ [<b>-h</b> <i>queue</i><b>_</b><i>id</i>] [<b>-H</b> <i>queue</i><b>_</b><i>id</i>]
+ [<b>-r</b> <i>queue</i><b>_</b><i>id</i>] [<i>directory ...</i>]
+
+<b>DESCRIPTION</b>
+ The <a href="postsuper.1.html"><b>postsuper</b>(1)</a> command does maintenance jobs on the Postfix queue.
+ Use of the command is restricted to the superuser. See the
+ <a href="postqueue.1.html"><b>postqueue</b>(1)</a> command for unprivileged queue operations such as listing
+ or flushing the mail queue.
+
+ By default, <a href="postsuper.1.html"><b>postsuper</b>(1)</a> performs the operations requested with the <b>-s</b>
+ and <b>-p</b> command-line options on all Postfix queue directories - this
+ includes the <b>incoming</b>, <b>active</b>, <b>deferred</b>, and <b>hold</b> directories with mes-
+ sage files and the <b>bounce</b>, <b>defer</b>, <b>trace</b> and <b>flush</b> directories with log
+ files.
+
+ Options:
+
+ <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>-d</b> <i>queue</i><b>_</b><i>id</i>
+ Delete one message with the named queue ID from the named mail
+ queue(s) (default: <b>hold</b>, <b>incoming</b>, <b>active</b> and <b>deferred</b>).
+
+ To delete multiple files, specify the <b>-d</b> option multiple times,
+ or specify a <i>queue</i><b>_</b><i>id</i> of <b>-</b> to read queue IDs from standard
+ input. For example, to delete all mail with exactly one recipi-
+ ent <b>user@example.com</b>:
+
+ mailq | tail -n +2 | grep -v '^ *(' | awk 'BEGIN { RS = "" }
+ # $7=sender, $8=recipient1, $9=recipient2
+ { if ($8 == "user@example.com" &amp;&amp; $9 == "")
+ print $1 }
+ ' | tr -d '*!' | postsuper -d -
+
+ Specify "<b>-d ALL</b>" to remove all messages; for example, specify
+ "<b>-d ALL deferred</b>" to delete all mail in the <b>deferred</b> queue. As
+ a safety measure, the word <b>ALL</b> must be specified in upper case.
+
+ Warning: Postfix queue IDs are reused (always with Postfix &lt;=
+ 2.8; and with Postfix &gt;= 2.9 when <a href="postconf.5.html#enable_long_queue_ids">enable_long_queue_ids</a>=no).
+ There is a very small possibility that postsuper deletes the
+ wrong message file when it is executed while the Postfix mail
+ system is delivering mail.
+
+ The scenario is as follows:
+
+ 1) The Postfix queue manager deletes the message that <a href="postsuper.1.html"><b>post-</b></a>
+ <a href="postsuper.1.html"><b>super</b>(1)</a> is asked to delete, because Postfix is finished
+ with the message (it is delivered, or it is returned to
+ the sender).
+
+ 2) New mail arrives, and the new message is given the same
+ queue ID as the message that <a href="postsuper.1.html"><b>postsuper</b>(1)</a> is supposed to
+ delete. The probability for reusing a deleted queue ID
+ is about 1 in 2**15 (the number of different microsecond
+ values that the system clock can distinguish within a
+ second).
+
+ 3) <a href="postsuper.1.html"><b>postsuper</b>(1)</a> deletes the new message, instead of the old
+ message that it should have deleted.
+
+ <b>-e</b> <i>queue</i><b>_</b><i>id</i>
+
+ <b>-f</b> <i>queue</i><b>_</b><i>id</i>
+ Request forced expiration for one message with the named queue
+ ID in the named mail queue(s) (default: <b>hold</b>, <b>incoming</b>, <b>active</b>
+ and <b>deferred</b>).
+
+ <b>o</b> The message will be returned to the sender when the queue
+ manager attempts to deliver that message (note that Post-
+ fix will never deliver messages in the <b>hold</b> queue).
+
+ <b>o</b> The <b>-e</b> and <b>-f</b> options both request forced expiration. The
+ difference is that <b>-f</b> will also release a message if it
+ is in the <b>hold</b> queue. With <b>-e</b>, such a message would not
+ be returned to the sender until it is released with <b>-f</b> or
+ <b>-H</b>.
+
+ <b>o</b> When a deferred message is force-expired, the return mes-
+ sage will state the reason for the delay. Otherwise, the
+ reason will be "message is administratively expired".
+
+ To expire multiple files, specify the <b>-e</b> or <b>-f</b> option multiple
+ times, or specify a <i>queue</i><b>_</b><i>id</i> of <b>-</b> to read queue IDs from stan-
+ dard input (see the <b>-d</b> option above for an example, but be sure
+ to replace <b>-d</b> in the example).
+
+ Specify "<b>-e ALL</b>" or "<b>-f ALL</b>" to expire all messages; for exam-
+ ple, specify "<b>-e ALL deferred</b>" to expire all mail in the
+ <b>deferred</b> queue. As a safety measure, the word <b>ALL</b> must be spec-
+ ified in upper case.
+
+ These features are available in Postfix 3.5 and later.
+
+ <b>-h</b> <i>queue</i><b>_</b><i>id</i>
+ Put mail "on hold" so that no attempt is made to deliver it.
+ Move one message with the named queue ID from the named mail
+ queue(s) (default: <b>incoming</b>, <b>active</b> and <b>deferred</b>) to the <b>hold</b>
+ queue.
+
+ To hold multiple files, specify the <b>-h</b> option multiple times, or
+ specify a <i>queue</i><b>_</b><i>id</i> of <b>-</b> to read queue IDs from standard input.
+
+ Specify "<b>-h ALL</b>" to hold all messages; for example, specify "<b>-h</b>
+ <b>ALL deferred</b>" to hold all mail in the <b>deferred</b> queue. As a
+ safety measure, the word <b>ALL</b> must be specified in upper case.
+
+ Note: while mail is "on hold" it will not expire when its time
+ in the queue exceeds the <b><a href="postconf.5.html#maximal_queue_lifetime">maximal_queue_lifetime</a></b> or
+ <b><a href="postconf.5.html#bounce_queue_lifetime">bounce_queue_lifetime</a></b> setting. It becomes subject to expiration
+ after it is released from "hold".
+
+ This feature is available in Postfix 2.0 and later.
+
+ <b>-H</b> <i>queue</i><b>_</b><i>id</i>
+ Release mail that was put "on hold". Move one message with the
+ named queue ID from the named mail queue(s) (default: <b>hold</b>) to
+ the <b>deferred</b> queue.
+
+ To release multiple files, specify the <b>-H</b> option multiple times,
+ or specify a <i>queue</i><b>_</b><i>id</i> of <b>-</b> to read queue IDs from standard
+ input.
+
+ Note: specify "<b>postsuper -r</b>" to release mail that was kept on
+ hold for a significant fraction of <b>$<a href="postconf.5.html#maximal_queue_lifetime">maximal_queue_lifetime</a></b> or
+ <b>$<a href="postconf.5.html#bounce_queue_lifetime">bounce_queue_lifetime</a></b>, or longer.
+
+ Specify "<b>-H ALL</b>" to release all mail that is "on hold". As a
+ safety measure, the word <b>ALL</b> must be specified in upper case.
+
+ This feature is available in Postfix 2.0 and later.
+
+ <b>-p</b> Purge old temporary files that are left over after system or
+ software crashes. The <b>-p</b>, <b>-s</b>, and <b>-S</b> operations are done before
+ other operations.
+
+ <b>-r</b> <i>queue</i><b>_</b><i>id</i>
+ Requeue the message with the named queue ID from the named mail
+ queue(s) (default: <b>hold</b>, <b>incoming</b>, <b>active</b> and <b>deferred</b>).
+
+ To requeue multiple files, specify the <b>-r</b> option multiple times,
+ or specify a <i>queue</i><b>_</b><i>id</i> of <b>-</b> to read queue IDs from standard
+ input.
+
+ Specify "<b>-r ALL</b>" to requeue all messages. As a safety measure,
+ the word <b>ALL</b> must be specified in upper case.
+
+ A requeued message is moved to the <b>maildrop</b> queue, from where it
+ is copied by the <a href="pickup.8.html"><b>pickup</b>(8)</a> and <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemons to a new queue
+ file. In many respects its handling differs from that of a new
+ local submission.
+
+ <b>o</b> The message is not subjected to the <a href="postconf.5.html#smtpd_milters">smtpd_milters</a> or
+ <a href="postconf.5.html#non_smtpd_milters">non_smtpd_milters</a> settings. When mail has passed through
+ an external content filter, this would produce incorrect
+ results with Milter applications that depend on original
+ SMTP connection state information.
+
+ <b>o</b> The message is subjected again to mail address rewriting
+ and substitution. This is useful when rewriting rules or
+ virtual mappings have changed.
+
+ The address rewriting context (local or remote) is the
+ same as when the message was received.
+
+ <b>o</b> The message is subjected to the same <a href="postconf.5.html#content_filter">content_filter</a> set-
+ tings (if any) as used for new local mail submissions.
+ This is useful when <a href="postconf.5.html#content_filter">content_filter</a> settings have changed.
+
+ Warning: Postfix queue IDs are reused (always with Postfix &lt;=
+ 2.8; and with Postfix &gt;= 2.9 when <a href="postconf.5.html#enable_long_queue_ids">enable_long_queue_ids</a>=no).
+ There is a very small possibility that <a href="postsuper.1.html"><b>postsuper</b>(1)</a> requeues the
+ wrong message file when it is executed while the Postfix mail
+ system is running, but no harm should be done.
+
+ This feature is available in Postfix 1.1 and later.
+
+ <b>-s</b> Structure check and structure repair. This should be done once
+ before Postfix startup. The <b>-p</b>, <b>-s</b>, and <b>-S</b> operations are done
+ before other operations.
+
+ <b>o</b> Rename files whose name does not match the message file
+ inode number. This operation is necessary after restoring
+ a mail queue from a different machine or from backup,
+ when queue files were created with Postfix &lt;= 2.8 or with
+ "<a href="postconf.5.html#enable_long_queue_ids">enable_long_queue_ids</a> = no".
+
+ <b>o</b> Move queue files that are in the wrong place in the file
+ system hierarchy and remove subdirectories that are no
+ longer needed. File position rearrangements are neces-
+ sary after a change in the <b><a href="postconf.5.html#hash_queue_names">hash_queue_names</a></b> and/or
+ <b><a href="postconf.5.html#hash_queue_depth">hash_queue_depth</a></b> configuration parameters.
+
+ <b>o</b> Rename queue files created with "<a href="postconf.5.html#enable_long_queue_ids">enable_long_queue_ids</a> =
+ yes" to short names, for migration to Postfix &lt;= 2.8.
+ The procedure is as follows:
+
+ # postfix stop
+ # postconf <a href="postconf.5.html#enable_long_queue_ids">enable_long_queue_ids</a>=no
+ # postsuper
+
+ Run <a href="postsuper.1.html"><b>postsuper</b>(1)</a> repeatedly until it stops reporting file
+ name changes.
+
+ <b>-S</b> A redundant version of <b>-s</b> that requires that long file names
+ also match the message file inode number. This option exists for
+ testing purposes, and is available with Postfix 2.9 and later.
+ The <b>-p</b>, <b>-s</b>, and <b>-S</b> operations are done before other operations.
+
+ <b>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b>
+ options make the software increasingly verbose.
+
+<b>DIAGNOSTICS</b>
+ Problems are reported to the standard error stream and to <b>syslogd</b>(8) or
+ <a href="postlogd.8.html"><b>postlogd</b>(8)</a>.
+
+ <a href="postsuper.1.html"><b>postsuper</b>(1)</a> reports the number of messages deleted with <b>-d</b>, the number
+ of messages expired with <b>-e</b>, the number of messages expired or released
+ with <b>-f</b>, the number of messages held or released with <b>-h</b> or <b>-H</b>, the
+ number of messages requeued with <b>-r</b>, and the number of messages whose
+ queue file name was fixed with <b>-s</b>. The report is written to the stan-
+ dard error stream and to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>.
+
