NAME

mailstats — print mail traffic statistics

SYNOPSIS

mailstats [-o] [-C cffile] [-f stfile]

DESCRIPTION

mailstats reads and interprets the sendmail statistics file, /etc/mail/sendmail.st, then prints out the mail traffic statistics. If /etc/mail/sendmail.st exists, sendmail collects statistics about your mail traffic and stores them in the statistics file. This file does not grow.

Statistics are gathered on a per-mailer basis for each mailer defined in the sendmail configuration file. Statistics are kept on the number of messages and the number of bytes for all inbound and outbound traffic.

The mailstats utility displays the time at which statistics collection was started on the first line. Then, the statistics of each mailer is displayed on a single line, each with the following white space separated fields (see the "EXAMPLES" section below):

M: The mailer number.
msgsfr: Number of messages from the mailer.
bytes_from: Kbytes from the mailer.
msgsto: Number of messages to the mailer.
bytes_to: Kbytes to the mailer.
msgsrej: Number of messages rejected.
msgsdis: Number of messages discarded.
Mailer: 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 containing only equals (``='') characters.

Options

The options are as follows:

-C: Read the specified file instead of the default /etc/mail/sendmail.cf file.
-f: Read the specified statistics file instead of the statistics file specified in the /etc/mail/sendmail.cf file.
-o: Do not display the name of the mailer in the output.

To clear the statistics file, execute, as root:

cp/dev/null/etc/mail/sendmail.st

RETURN VALUE

The mailstats utility exits 0 on success, and >0 if an error occurs.

DIAGNOSTICS

mailstats generates error messages if the statistics file is not accessible or if the size of the statistics file has changed. Error messages are:

mailstats: file size changed: Either /etc/mail/sendmail.st 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.
mailstats: /etc/mail/sendmail.st: No such file or directory: The statistics file does not exist.
mailstats: /etc/mail/sendmail.st: Permission denied: The statistics file's permissions are set so that you cannot read it.

EXAMPLES

Here is a typical example of mailstats output:

Statistics from Thu Jul 11 14:12:40 1996 
M   msgsfr  bytes_from   msgsto    bytes_to  msgsrej msgsdis  Mailer 
0        0          0K        3          4K        0       0  prog 
3        3          4K        0          0K        0       0  local 
5        2          1K       11         11K        4       0  esmtp 
=============================================================
T       13         13K       14         15K        4       0 

This example shows that mailers 0, 3 and 5 have handled the given amounts of mail traffic since Thursday, Jul 11th. Specifically, sendmail has sent 11 messages containing 11 kilobytes via mailer esmtp (M 5), but has 4 messages rejected via mailer esmtp (M 5).
