You'll want to use yum shell to remove the CentOS stock packages and
replace them with the GFD ones in a single step.

I've documented the process for postfix here, dovecot works pretty much
the same in that regard.

One caveat about dovecot is that the config is not as reliably backwards
compatible to previous major versions as postfix is.  You will likely
have to do some tweaking of settings in order to get it to run again.
If you're on a production system and this worries you then I recommend
you fire up a test box or VM and trial it out first.
