I tend to agree with that senario and have mostly followed that
conguration in my mid to high volume servers.  I also keep the DNS
seperated and network diverse.  I also do things like install multiple
nics to allow "backhauling" the processed mail to the POP/IMAP machine(s)
via a private dedicated lan and not sending it back out the world
interface it came in on.

I do have a few installations where the seperation of function would be
like having 2 engines in a car, one to run the front wheels and one to run
the back.
