Using virtual accounts (LDAP), a global uid/gid for all users and a few
PHP scripts I've been able to setup something along these lines.  The web
page script requires an administrator authentication, the admin can then
specify a user's account and a special account is symlinked to that user's
home directory.  i.e. The admin wants to look at JDOE's mailbox, after
authenticating and choosing JDOE, the PHP script symlinks /var/mail/JDOE
to /var/mail/IS_STAFF.  The admin can then login as IS_STAFF and see all
of JDOE's IMAP folders as JDOE would.  Not sure about the wisdom of this
approach but it works for me.
