It is nice to have, but the only time I seriously used it was
back in school. I would schedule at to print out a document in a
few minutes, providing me just enough time to get from my dorm
room to the computer lab and have the last page printed out as I
walked through the door. It took a few tries to get it just right.

ps auxww | grep cron
chkconfig --list | grep :on | grep cron

You mean syslog? See /var/log.

Using an external host, telnet to tcp/25 with the firewall
enabled and disabled. Or not run sendmail in listening mode
(run only -q instead of -bd). Or use a better MTA.

I would recommend you pick up "UNIX System Administration
Handbook", ISBN: 0130206016. It is the SA bible. There is a Linux
version as well.
