How do I suppress or amend the “Fax Usage Report” which is emailed to FaxMaster daily?
Chances are you’ve installed a HylaFAX package, such as an RPM, that has set this report up as a cron job. On Red Hat, look at /etc/cron.daily/hylafax, and comment out the faxcron line. Each package/distro will be different, but the genral process is the same – find the cron job and deactivate (or customize) the running of it.
