Recent Red Hat sendmail rpms come configured to only bind to
localhost, which is why it works if you telnet from localhost.  It
does not listen on any external interfaces.

If you look in /etc/mail/sendmail.mc, you'll find this:

  dnl This changes sendmail to only listen on the loopback device 127.0.0.1
  dnl and not on any other network devices. Comment this out if you want
  dnl to accept email over the network.
  DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')

insert 'dnl' infront of that last line, and then run the following
commands (as root):

  cp /etc/sendmail.cf /etc/sendmail.cf.bak
  m4 /etc/mail/sendmail.mc > /etc/sendmail.cf
  /etc/init.d/sendmail restart

Your problem should be solved.
