Hello !
Despite Redhat ships sendmail et Postfix, you can benefit from using the
new "alternatives" capability available since Redhat 7.3.
It behaves like the debian alternatives package.
So you can use this little script to declare Exim as an MTA alternative
and activate it ! It is a non destructive approach based on symlinks.
Mixed with your initscript it's IMHO quite a good way to install Exim.

You can tweak this cmdline to fit your needs ....
# misc commands to test and activate .... man alternatives is your
friend
# alternatives --display mta

/usr/sbin/alternatives --install /usr/sbin/sendmail mta /usr/sbin/exim 90 \
--slave /usr/bin/mailq mta-mailq /usr/sbin/exim \
--slave /usr/bin/newaliases mta-newaliases /usr/bin/newaliases.sendmail \
--slave /usr/bin/rmail mta-rmail /usr/sbin/exim \
--slave /usr/share/man/man1/mailq.1.gz mta-mailqman /usr/share/man/man1/mailq.sendmail.1.gz \
--slave /usr/share/man/man1/newaliases.1.gz mta-newaliasesman /usr/share/man/man1/newaliases.sendmail.1.gz \
--slave /usr/share/man/man5/aliases.5.gz mta-aliasesman /usr/share/man/man5/aliases.sendmail.5.gz \
--initscript exim

#
# alternatives --set mta /usr/sbin/exim
