Next we need to check and see what's installed. If you did a complete installation of sendmail you will have three RPMs installed; sendmail, sendmail-cf, and sendmail-doc. The quickest way to check this is to issue this command:
[root@ntbox /root]# rpm -qa|grep 'sendmail' sendmail-doc-8.9.3-15 sendmail-8.9.3-15 sendmail-cf-8.9.3-15
As you can see from the response we got from our test machine we had all three of them installed prior to beginning our test procedure.
