By default, SMTP servers on RHEL systems only listen to localhost, not the
network interface. Chances are you need to put "dnl " in front of the
line "DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl" in your
/etc/mail/sendmail.mc ...
run m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
and restart sendmail

Before you do this, try :

telnet localhost 25

If that answers, then the above fix should work.

Did you put 'dnl' in front of that line before rebuilding the
sendmail.cf? What you have above tells sendmail only to listen on the
loopback interface.

What is the output of

grep DAEMON_OPTIONS /etc/mail/sendmail.mc

What is the output of

netstat -tnlp | grep LISTEN | grep 25
