+.SH DESCRIPTION
+.ad
+.fi
+The \fBqshape\fR program helps the administrator understand the
+Postfix queue message distribution in time and by sender domain
+or recipient domain. The program needs read access to the queue
+directories and queue files, so it must run as the superuser or
+the \fBmail_owner\fR specified in \fBmain.cf\fR (typically
+\fBpostfix\fR).
+
+Options:
+.IP \fB\-s\fR
+Display the sender domain distribution instead of the recipient
+domain distribution.  By default the recipient distribution is
+displayed. There can be more recipients than messages, but as
+each message has only one sender, the sender distribution is a
+message distribution.
+.IP \fB\-p\fR
+Generate aggregate statistics for parent domains. Top level domains
+are not shown, nor are domains with fewer than \fImin_subdomains\fR
+subdomains. The names of parent domains are shown with a leading dot,
+(e.g. \fI.example.com\fR).
+.IP "\fB\-m \fImin_subdomains\fR"
+When used with the \fB\-p\fR option, sets the minimum subdomain count
+needed to show a separate line for a parent domain. The default is 5.
+.IP "\fB\-b \fIbucket_count\fR"
+The age distribution is broken up into a sequence of geometrically
+increasing intervals. This option sets the number of intervals
+or "buckets". Each bucket has a maximum queue age that is twice
+as large as that of the previous bucket. The last bucket has no
+age limit.
+.IP "\fB\-t \fIbucket_time\fR"
+The age limit in minutes for the first time bucket. The default
+value is 5, meaning that the first bucket counts messages between
+0 and 5 minutes old.
+.IP "\fB\-l\fR"
+Instead of using a geometric age sequence, use a linear age sequence,
+in other words simple multiples of \fBbucket_time\fR.
+
+This feature is available in Postfix 2.2 and later.
+.IP "\fB\-w \fIterminal_width\fR"
+The output is right justified, with the counts for the last
+bucket shown on the 80th column, the \fIterminal_width\fR can be
+adjusted for wider screens allowing more buckets to be displayed
+without truncating the domain names on the left. When a row for a
+full domain name and its counters does not fit in the specified
+number of columns, only the last 17 bytes of the domain name
+are shown with the prefix replaced by a '+' character. Truncated
+parent domain rows are shown as '.+' followed by the last 16 bytes
+of the domain name. If this is still too narrow to show the domain
+name and all the counters, the terminal_width limit is violated.
+.IP "\fB\-N \fIbatch_msg_count\fR"
+When the output device is a terminal, intermediate results are
+shown each "batch_msg_count" messages. This produces usable results
+in a reasonable time even when the deferred queue is large. The
+default is to show intermediate results every 1000 messages.
+.IP "\fB\-n \fIbatch_top_domains\fR"
+When reporting intermediate or final results to a termainal, report
+only the top "batch_top_domains" domains. The default limit is 20
+domains.
+.IP "\fB\-c \fIconfig_directory\fR"
+The \fBmain.cf\fR configuration file is in the named directory
+instead of the default configuration directory.
+.PP
+Arguments:
+.IP \fIqueue_name\fR
+By default \fBqshape\fR displays the combined distribution of
+the incoming and active queues. To display a different set of
+queues, just list their directory names on the command line.
+Absolute paths are used as is, other paths are taken relative
+to the \fBmain.cf\fR \fBqueue_directory\fR parameter setting.
+While \fBmain.cf\fR supports the use of \fI$variable\fR expansion
+in the definition of the \fBqueue_directory\fR parameter, the
+\fBqshape\fR program does not. If you must use variable expansions
+in the \fBqueue_directory\fR setting, you must specify an explicit
+absolute path for each queue subdirectory even if you want the
+default incoming and active queue distribution.
