MAILSTATS(1)MAILSTATS(1)NAMEmailstats - print statistics collected by sendmail
SYNOPSISmailstats [-o] [-c ] [-C configfile] [-f statisticsfile]
[-p] [-P]
DESCRIPTION
The mailstats utility prints out the statistics collected by the send‐
mail(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-sep‐
arated 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
