On RHEL, if you co-install sendmail and postfix (exim isn't in the regular repo; it must be in EPEL since it's in Fedora), /sbin/sendmail is a symlink to /etc/alternatives/mta and /etc/alternatives/mta is a symlink to /sbin/sendmail.sendmail or /sbin/sendmail.postfix, with a similar setup for the sendmail man page. But their startup scripts/units conflict and have to be modified to be co-runnable.
