The solution we have for this "email folder sharing" is to implement it
via WebMail. WebMail can take care of the access controls and
permission levels and can know the passwords to access the individual
folders and such. If done well, it can behave exactly as you describe
for folders explicitly shared with the secretary. The benefit is that
you do not need to do anything with symlinks and permissions (which I
think could work but could result in some problems for non-single file
folder formats -- i.e. with mixed ownership of files an d ensuring
consistent permissions for all files and subfolders).
Our WebMail solution at http://luxsci.com has this exact kind of email
sharing functionality on top of a UW IMAP back end. If you have
questions on how you could implement it yourself.
