OK, some things to check:
Is /usr/sbin/sendmail and /usr/lib/sendmail a symlink to
/var/qmail/bin/sendmail
Are the qmail processes (which you start with '/var/qmail/rc &' in
/etc/rc.d/rc.local) running. Run 'ps -ef | grep qmail' and see if Qmail
is there.
And, since you mentioned that you are a Newbie sysadmin using RH7, please,
pretty please update (or get rid of) the various remote root exploits that
RedHat 7 comes with. More information at:

A Linux box that can be remotely rooted is a headache to the entire
internet community.
