If it is a default CentOS install, you should have sendmail installed,
but you probably need to install sendmail-cf and create a site specific
sendmail.cf file (from a site specific sendmail.mc file).

Look in /var/log/maillog for error messages.

The 'mail' command is the correct thing to use, except you need to bind
stdin to something. Eg:

df -h | mail -s "Disk space report" mumble at whatever.com

or

mail -s "Disk space alert!" mumble at whatever.com </dev/null
