It is even pretty simple to switch off the sendmail daemon and only run the queueing submission agent:
- edit /etc/sysconfig/sendmail and set "DAEMON=no"
- edit /etc/mail/submit.mc and set FEATURE(`msp', `[IP.of.relayhost]')dnl
Given the sendmail-cf RPM is already installed a "service sendmail restart" is enough to a light, direct submitting sendmail setup.

Nice, I only asked about Postfix is that's all I sort-of know. But this helps in that I don't have to install Postfix then switch-mail if sendmail is installed already.
