Use of the command is restricted to the superuser. +See the \fBpostqueue\fR(1) command for unprivileged queue operations +such as listing or flushing the mail queue. + +By default, \fBpostsuper\fR(1) performs the operations +requested with the +\fB\-s\fR and \fB\-p\fR command\-line options on all Postfix queue +directories \- this includes the \fBincoming\fR, \fBactive\fR and +\fBdeferred\fR directories with mail files and the \fBbounce\fR, +\fBdefer\fR, \fBtrace\fR and \fBflush\fR directories with log files. + +Options: +.IP "\fB\-c \fIconfig_dir\fR" +The \fBmain.cf\fR configuration file is in the named directory +instead of the default configuration directory. See also the +MAIL_CONFIG environment setting below. +.IP "\fB\-d \fIqueue_id\fR" +Delete one message with the named queue ID from the named +mail queue(s) (default: \fBhold\fR, \fBincoming\fR, \fBactive\fR and +\fBdeferred\fR). + +To delete multiple files, specify the \fB\-d\fR option multiple +times, or specify a \fIqueue_id\fR of \fB\-\fR to read queue IDs +from standard input.

It becomes subject to +expiration after it is released from "hold". +.sp +This feature is available in Postfix 2.0 and later. +.IP "\fB\-H \fIqueue_id\fR" +Release mail that was put "on hold". +Move one message with the named queue ID from the named +mail queue(s) (default: \fBhold\fR) to the \fBdeferred\fR queue. + +To release multiple files, specify the \fB\-H\fR option multiple +times, or specify a \fIqueue_id\fR of \fB\-\fR to read queue IDs +from standard input. +.sp +Note: specify "\fBpostsuper \-r\fR" to release mail that was kept on +hold for a significant fraction of \fB$maximal_queue_lifetime\fR +or \fB$bounce_queue_lifetime\fR, or longer. +.sp +Specify "\fB\-H ALL\fR" to release all mail that is "on hold". +As a safety measure, the word \fBALL\fR must be specified in upper +case. +.sp +This feature is available in Postfix 2.0 and later. +.IP \fB\-p\fR +Purge old temporary files that are left over after system or +software crashes. +.IP "\fB\-r \fIqueue_id\fR" +Requeue the message with the named queue ID from the named +mail queue(s) (default: \fBhold\fR, \fBincoming\fR, \fBactive\fR and +\fBdeferred\fR). + +To requeue multiple files, specify the \fB\-r\fR option multiple +times, or specify a \fIqueue_id\fR of \fB\-\fR to read queue IDs +from standard input. +.sp +Specify "\fB\-r ALL\fR" to requeue all messages. As a safety +measure, the word \fBALL\fR must be specified in upper case. +.sp +A requeued message is moved to the \fBmaildrop\fR queue, +from where it is copied by the \fBpickup\fR(8) and +\fBcleanup\fR(8) daemons to a new queue file. In many +respects its handling differs from that of a new local +submission. +.RS +.IP \(bu +The message is not subjected to the smtpd_milters or +non_smtpd_milters 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. +.IP \(bu +The message is subjected again to mail address rewriting +and substitution. This is useful when rewriting rules or +virtual mappings have changed. +.sp +The address rewriting context (local or remote) is the same +as when the message was received. +.IP \(bu +The message is subjected to the same content_filter settings +(if any) as used for new local mail submissions.
