SYNOPSIS
cffile] stfile]
DESCRIPTION
reads and interprets the statistics file, and then prints out the mail
traffic statistics. The statistics file is the one set by the option
in the The default statistics file is If the statistics file exists,
collects statistics about your mail traffic and stores them in that
file. This file does not grow.
Statistics are gathered on a per-mailer basis for each mailer defined
in the configuration file. Statistics are kept on the number of mes‐
sages and the number of bytes for all inbound and outbound traffic.
The utility displays the time at which statistics collection was
started on the first line. Then, the statistics of each mailer is dis‐
played on a single line, each with the following white space separated
fields (see the "EXAMPLES" section below):
The mailer number.
Number of messages from the mailer.
Kbytes from the mailer.
Number of messages to the mailer.
Kbytes to the mailer.
Number of messages rejected.
Number of messages discarded.
The name of the mailer.
After this display, a line totaling the values for all of the mailers
is displayed, separated from the previous information by a line con‐
taining only equals (``='') characters.
Note
can be used by privileged users only.

RETURN VALUE
The utility exits with 0 on success, and >0 if an error occurs.
DIAGNOSTICS
generates error messages if the statistics file is not accessible or if
the size of the statistics file has changed. Error messages are:
Either statistics-file is zero length, meaning that no mail has
been transferred since it was cleared out, or its size
has changed. Since the size of this file is supposed to
remain constant, any change in size means that the file
is invalid.
The statistics file does not exist.
The statistics file's permissions are set so that you cannot
read it.
