NAME

mailstats − print mail traffic statistics

SYNOPSIS

mailstats

DESCRIPTION

Mailstats reads and interprets the sendmail statistics file, /usr/lib/sendmail.st, and then prints out the mail traffic statistics.  If /usr/lib/sendmail.st exists, sendmail will collect statistics about your mail traffic and store 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. 

“grep ’^M’ /usr/lib/sendmail.cf” will show the definitions of the mailers (delivery agents) reported on by mailstats. The first one listed is mailer 0 , the second is mailer 1, etc. 

DIAGNOSTICS

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

ERROR (mailstats): Stat file size has changed or is zero in length

The size of /usr/lib/sendmail.st has changed.  Since the size of this file is supposed to remain constant, any change in size signifies that the file has been corrupted. 

Open: /usr/lib/sendmail.st: No such file or directory

The file’s permissions are not set so that you can read it or the file does not exist. 

/usr/lib/sendmail.st: Permission denied

The file’s permissions are not set so that you can read it. 

EXAMPLES

Here is a typical example of mailstats command output:

Statistics from Fri Dec  6 12:34:47 1985
M msgsfr  bytes_from  msgsto  bytes_to
0    216        318K      68       76K
3     80        108K      75      124K
4      0          0K      60       64K

This example shows that mailers 0, 3 and 4 have handled the given amounts of mail traffic since Friday, December 6th.  Specifically, sendmail has sent 60 messages containing 64K bytes via mailer number 4, but hasn’t received any inbound messages via mailer number 4. 

DEPENDENCIES

Implemented on the Series 300 and 800 only.
