Shouldn't these be 'proxyd' instead of 'imapd'?

And I think this should be lmtpproxyd.

Is the mupdate master on another server? If not (and you intend for
imapd_fe.conf to be the mudpate master), you need to specify a -m parameter
to mupdate here.

What does your imapd_fe.conf look like?
Do:
ctl_mboxlist -C /etc/imapd_fe.conf -d
ctl_mboxlist -C /etc/imapd_be.conf -d
and see if the output is sensible. The output of the backend should
reference a local partition for the location of your mailboxes ('default'),
and should not reference a remote server.
In the frontend mailbox list output, you should see the location of the
mailbox list pointing to <backend>!default, or something that resolves
(uniquely) to the backend.
