I just got the following mail from my server. I didn't install/update webmin manually, it's there as it has always been since I've set it up over a year ago. Is this just a normal regular automatic update mail, or should I be worried?
Anacron job 'cron.daily' on mail.mydomain.com
/etc/cron.daily/0yum.cron: Webmin install complete. You can now login to https://mail.mydomain.com:10000/ as root with your root password.
