I have been running
logwatch (installed via MacPorts) on my home Macs for at least a year.
logwatch --mailto root
Very recently my daily reports stopped showing up in my mail. I never like to see (not see) this happen.
Different versions of OS X.
Running things manually seems to work, but nightly job fails to send the mail report.
Chase things on the web, not much help, well, lots of false alarms. I finally saw a hint to turn off Apple’s org.postfix.master. I did that and voila, my
logwatch mail started flowing again.
