symlinks to implement shared mail folders?  Is this the official
recommendation from dovecot on how to implement this?  If dovecot
dumps any of its own data (subscription/other) files into mail
folders, then this kind of symlinking is bound to break IMO.  You need
to take this whole design to the dovecot community and make sure it
really will work before you try to figure out if it will work via
webmail.  If you insist on solving a server problem using a client,
though, turn up your IMAP logging verbosity or sniff the connection
between webmail and IMAP to see the commands and responses and errors
dovecot is throwing.
