Have you done the obvious and tried to reboot the machine?  If you have,
then ssh/telnet in and do:

ps auxw | grep sendmail

check to see if there are any listings like below.

root       676  0.0  0.8  2060 1080 ?        S    Sep26   0:00 sendmail:
accepting connections on port 25

If not then check /var/log/messages and see why, possibly, sendmail is not
starting.

You can also try doing:

/etc/rc.d/init.d/sendmail restart

and see what happens then.

Good luck.
