Yes, they can. Cron can work whether you know about it or not
eg. "journalctl | grep cron | less 
# man journalctl if worried

you can always flag on "warning, fail, etc.."

If you have just installed Fedora from F20+
yum install mta (of choice, if required)

That depends if you have it setup to receive or not.

That's because (MTA) hasn't been obsoleted
