Thanks for your answer. I did check to see if sendmail is installed, but it's installed differently and I suspect that is because it is installed on a 64-bit system. I can also use mail to send myself email using our email server.
root 3551 1 0 May20 ? 00:00:00 sendmail: accepting connections
smmsp 3558 1 0 May20 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
/usr/bin/which: no sendmail in (PATH:/sbin:/bin:/usr/local/bin:/usr/bin:/root/bin)

I checked on my system this way:
$ which sendmail
$rpm -qf /usr/sbin/sendmail
I'm running Fedora 13, but should be similar on your redhat machine
