I have a few cron jobs which periodically check my RAID status and disk usage. I would like to have the outcome emailed to myself. The proper syntax for sending mail through terminal is mail -s "subject" email@example.com, however nothing is sent. I know my cron jobs work as I had the outputs redirected to a file. How does the mail application know what mail server to send the email through? If it used the recipients email server, what happens if it requires authentication? How can I configure the /usr/bin/mail command to use a specific smpt server?
