mailstats - print mail traffic statistics
mailstats [-o] [-C cffile] [-f stfile]
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
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.
The options are as follows:
-C Read the specified file instead of the default
-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:
The mailstats utility exits 0 on success, and >0 if an error occurs.
mailstats generates error messages if the statistics file is not
accessible or if the size of the statistics file has changed. Error
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
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
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).
mailstats was developed by the University of California, Berkeley.
