I am getting the following error on giving service sendmail start command:

Starting sendmail: 554 5.0.0 No local mailer defined
554 5.0.0 QueueDirectory (Q) option must be set

I have sendmail installed on my system. The details are:
Name : sendmail
Version : 8.13.8
Vendor: Red Hat, Inc.
Release : 2.el5

Now I need to install sendmail-cf since the command m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf gave the following error:

/etc/mail/sendmail.mc:10: m4: cannot open `/usr/share/sendmail-cf/m4/cf.m4': No such file or directory

How to install sendmail-cf without using yum since I don't have yum installed on my system.
