 MAILSTATS 1 "Jun 24, 2004"
 NAME
mailstats - print statistics collected by sendmail
 SYNOPSIS

mailstats [-o] [-c ] [-C configfile] [-f statisticsfile]
 [-p] [-P]


 DESCRIPTION

The mailstats utility prints out the statistics collected by the
sendmail(1M) program on mailer usage. These statistics are collected if
the file indicated by the StatusFile configuration option of
sendmail (defined in /etc/mail/sendmail.cf) exists. The default
statistics file is /etc/mail/statistics.

To enable mailstats, you must, as root, touch /etc/mail/statistics.
See the StatusFile processing option in sendmail(1M).

mailstats first prints the time that the statistics file was created and
the last time it was modified. Then, the statistics for each mailer are
displayed on a single line, each with the following whitespace-separated
fields:
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 by the mailer.


msgsdis

Number of messages discarded by the mailer.


msgsqur

Number of messages quarantined by the mailer.


Mailer

The name of the mailer.


The display of statistics described above is followed by a separation line
containing only equal sign (=) characters. After the separation line, a
line preceded with a "T" and totaling the values for all of the mailers
is displayed. This is followed by another line preceded with a "C" that
lists the number of TCP connections.

To reinitialize the statistics file once a night, add an entry to root's
crontab(1):
mailstats -p > /dev/null

-c
