You *can* have imapd run on the same server as the homedirs are. What
you can't (or shouldn't) do is leave open any kind of access to the
mailstore because there's no guarantee that a random app the user decides
to use won't corrupt the folders by accessing them as local files.
IMHO the main point of separating the mailstore is that you can then
control how the mailstore is written to.
So if you want to have your imap and nfs services on the same machine,
that's more or less OK, but don't NFS-export the mailstore, and don't
give users unrestricted shell access on the machine.
