Displaying mailer information
The statistics kept in the /etc/mail/statistics file are in a database format that cannot be read as a text file.
To display the mailer statistics, type the following at a command prompt:
/usr/sbin/mailstats
This reads the information in the /etc/mail/statistics file, formats it, and writes it to standard output. For more information, see the /usr/sbin/mailstats command.
