The following script was included with the RH 7.1 Exim 3.36 (I think it
was 3.36) RPM. The file is called "exim" and it resides in the
directory "/etc/rc.d/init.d/" You also need to add the appropriate
links to the /etc/rc?.d/ directories, in order to get it to start at
boot time. See "man chkconfig" for details. Feel free to cut and paste
this. BTW I think I might have changed the default QUEUE value.
Whatever works for you.

I completely uninstalled Sendmail from my servers, and have not run into
any problems.
