Yup.  I posted about this quite awhile ago (more than a year), and STILL
have not gotten around to implementing the feature idea I had:

Allow ':' to separate the user name from a named module which will
limit the folders shown to the client.  eg by logging in as
'frank:subscribed' instead of 'frank', the IMAP client is never
even informed of non-subscribed folders.  The module names are
arbitrary and 'subscribed' in my example is just that, an example.

':' is generally an illegal username character so using it as a
separator should prove to not be a problem.

Doing some kind of shared folder thing on the server would probably
work as a hack today.  Login as the alternate user, who has permissions
on the subscribed folders of the real user, to see only those folders.
