Email only being sent on system reboot
I'm working on a FC 19 linux box.
I'm not very familiar with how to setup and administer email.
I have set up logwatch to email me summaries of activity and security alerts once a day, but I never see the emails until I reboot the OS. If it's been several days since I rebooted, I get all the emails sent to root during those several days.
I know I'm doing something wrong, but I don't know what to do. Can anyone help, or give me more diagnostic steps to post here?
