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.
